Commit Message

Buddhabhatti, Jay Nov. 9, 2023, 7 a.m. UTC 
  System-level platform management layer (do_fw_call()) has support for
maximum of 5 arguments as of now (1 EEMI API ID + 4 command arguments).
In order to support new EEMI PM_IOCTL IDs (Secure Read/Write), this
support must be extended to support one additional argument, which
results in a configuration of - 1 EEMI API ID + 5 command arguments.

Update zynqmp_pm_invoke_fn() and do_fw_call() with this new definition
containing variable arguments. As a result, update all the references
to pm invoke function with the updated definition.

FWIW, this is saying that num_args should be 'int' or 'unsigned int',
see commit be24b37e22c2 ("KEYS: trusted: fix -Wvarags warning") for
another instance of this problem.
