Currently, there is common feature check function for firmware APIs
and TF-A specific APIs. This should be separate from firmware APIs.
So add new TF-A API for feature check of TF-A specific APIs.

Currently, the IDs used in PLM CMD header are mixed with SMC IDs in
TF-A which is restricting the range of IDs that can be used by PLM.
Also, the SMC call from firmware driver is passing all 7 32-bit
words in request but TF-A is not passing all of them to firmware and
TF-A passes only 4 32-bit words from firmware to Linux in response.
So, update TF-A to passthrough all PLM commands by having a single
fixed SMC ID for all PLM commands and keep the PLM header in subsequent
SMC arguments. Also, enhance size of payload argument count to support
maximum payloads in request and response buffers to transmit all the
IPI command properly.

Today, the PM_IOCTL and PM_QUERY_DATA APIs are there to maintain
backward compatibility. Now, the usage of these APIs on the Linux
side and the firmware side is updated. Hence remove the deprecated
PM_IOCTL and PM_QUERY_DATA EEMI API from the TF-A to make TF-A pass
through.
Note: Only use the newer kernel to access the deprecated features in
this patch. Otherwise, the system may not function correctly.

For TF-A, there is no format specified for functional documentation.
For AMD-Xilinx platforms, following kernel-doc format for the functional
documentation to make sure AMD-xilinx documentation is align with
actual code.
For example use kernel-doc from linux to call:
<linux>/scripts/kernel-doc -man -v 1 >/dev/null file...

Add support for PM API SYS to get the chip ID from the target.
The API calls the IPI command to read the Chip idcode and revision.
