Cortex-A15 does not support FEAT_CSV2 so the existing workaround for
Spectre V2 is sufficient to mitigate against Spectre BHB attacks,
however the code needed to be updated to work with the new build flag.
Also, some code was refactored several years ago and not updated in
the Cortex-A15 library file so this patch fixes that as well.

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
