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.

Firmware supports new IOCTL for different purposes. To avoid
maintaining new IOCTL IDs in ATF, pass IOCTL call to firmware
for IOCTL IDs implemented in firmware.

Add support for runtime feature configuration which are running on the
firmware. Add new IOCTL IDs like IOCTL_SET_FEATURE_CONFIG and
IOCTL_GET_FEATURE_CONFIG for configuring the features.

Sync IOCTL IDs in order to avoid conflict with other components like,
Linux and firmware. Hence assigning value to IDs to make it more
specific.

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.
The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.
The exceptions are files that are imported from other projects:
- CryptoCell driver
- dt-bindings folders
- zlib headers

Since the MMIO read/write APIs are removed from Linux user space,
Linux cannot directly write to the Global General Storage Register 4
any more to set healthy boot status.
Create an IOCTL to allow Linux to set boot health status.

To make ULPI transceiver work, a HIGH - LOW - HIGH pulse needs
to be given to resetb pin of ULPI chip. In ZYNQMP, this resetb
pin is being driven by BOOT MODE PIN 1. The BOOT MODE PIN's
are controlled by BOOT_PIN_CTRL register present in CRL_APB
address region. Since CRL_APB can be resticted to secure access,
this pin should be controlled by ATF.
This patch adds the support for the same.
