This call is used to register and reset SGI interrupt.
Before this functionality was performed using IOCTL_REGISTER_SGI
pm_ioctl EEMI call. It's not correct use of PM_IOCTL as it is
not EEMI functionality. Instead this new SMCCC call will be
handled by TF-A specific handler.

Enable ARM_XLAT_TABLES_LIB_V1 as ZynqMP is using
v1 library of translation tables.
With upstream patch d323af9e3d,
the usage of MAP_REGION_FLAT is referring to definition in file
include/lib/xlat_tables/xlat_tables_v2.h but while preparing
xlat tables in lib/xlat_tables/xlat_tables_common.c it is referring
to include/lib/xlat_tables/xlat_tables.h which is v1 xlat tables.
Also, ZynqMP was using v1 so defined ARM_XLAT_TABLES_LIB_V1 to
use v1 xlat tables everywhere.
This fixes the issue of xlat tables failures as it takes v2
library mmap_region structure in some files and v1 in other
files.

The patch does below things.
1. As per current implementation, when Linux send a request to ATF to
get the version of APIs which are implemented in ATF then ATF wasn't
returning any version because there is a check for LIBPM module id.
The ATF is used to return version for the APIs which are implemented
in the firmware only.
Hence moved this switch-case before checking module id to get ATF
version.
Also, no need to pass Linux request to the firmware for the APIs
which are implemented in ATF instead return success after updating
version.
2. As per current implementation, higher 16-bit is used for ATF
version and lower 16-bit is used for firmware version. Now, removed
16-bit shift operation and send complete word i.e. 32-bit to Linux
user as there is no user who checks ATF version.
3. Add bit mask support in the feature check PM EEMI API for QUERY and
IOCTL ids.

Currently, SMC handler is limited to parsing 5 arguments (1 API ID + 4
32-bit command args). Extend this handling to support one more 32-bit
command argument which is necessary to support new IOCTL IDs for
secure read/write interface.
Note that, this change is completely transparent and does not affect
existing functionality of any of the EEMI APIs.

This change adds common interfaces to handle commands from firmware driver
to power management controller. It removes big chunk of source line of code
that was handling each command separately and doing same repetitive work.
EEMI - Embedded Energy Management Interface is Xilinx proprietary
protocol to allow communication between power management controller
and different processing clusters.
As of now, Each EEMI command has its own implementation in TF-A.
This is redundant. Essentially most EEMI command implementation
in TF-A does same work. It prepares payload received from kernel, sends
payload to firmware, receives response from firmware and send response
back to kernel.
The same functionality can be achieved if common interface is used among
multiple EEMI commands. This change divides platform management related
SMCCC requests into 4 categories.
1) EEMI commands required for backward compatibility.
Some EEMI commands are still required for backward compatibility
until removed completely or its use is changed to accommodate
common interface
2) EEMI commands that require for PSCI interface and accessed from debugfs
For example EEMI calls related to CPU suspend/resume
3) TF-A specific requests
Functionality such as getting TF-A version and getting callback
data for platform management is handled by this interface
4) Common interface for rest of EEMI commands
This handlers performs payload and firmware response transaction job for
rest of EEMI commands. Also it parses module ID from SMC payload and inserts
in IPI request. If not module ID is found, then default is LIBPM_MODULE_ID.
This helps in making common path in TF-A for all the modules in PLM firmware

If APU is in suspending state and if wakeup request comes then
PMUFW returns error which is not handled at ATF side.
To fix this, get the APU node status before calling wakeup and
return error if found in suspending state.
Here, we can not handle the error code of pm_req_wakeup() from PMUFW
because ATF is already calling pm_client_wakeup() before calling
pm_req_wakeup().

This API returns version of supported APIs.
Here, there are three cases to check API version by using feature
check implementation.
1. Completely implemented in TF-A: I mean the EEMI APIs which are
completely implemented in the TF-A only. So check those IDs and
return appropriate version for the same. Right now, it is base
version.
2. Completely implemented in firmware: I mean the EEMI APIs which are
completely implemented in the firmware only. Here, TF-A only passes
Linux request to the firmware to get the version of supported API. So
check those IDs and send request to firmware to get the version and
return to Linux if the version is supported or return the error code
if the feature is not supported.
3. Partially implemented (Implemented in TF-A and firmware both):
First check dependent EEMI API version with the expected version in
the TF-A. If the dependent EEMI API is supported in firmware then
return its version and check with the expected version in the TF-A.
If the version matches then check for the actual requested EEMI API
version. If the version is supported then return version of API
implemented in TF-A.
