feat(xilinx): remove PM_IOCTL and PM_QUERY_DATA APIs

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.
