xilinx: versal: Updated Response of QueryData API call

For the current XilPM calls, The handler of IPI returns information
with 16 Bytes data.
So during QueryData API call for the ClockName and PinFunctionName,
response data(name of clock or function) response[0..3] are used to
return name. And status is not being returned for such API.

Updated XilPM calls reply in a consistent way and The handler of IPI
return information with 32Bytes data. Where response[0] always set
to status.
For the version-2 of QueryData API, during call for the ClockName
and PinFunctionName, response data(name of clock or function) get as
response[1...4].

To support both the version of QueryData API, added version based
compatibility by the use of feature check.

xilinx: versal: Do not pass ACPU0 always in set_wakeup_source()

Existing code passes ACPU0 to LibPM as node_id in set_wakeup_source()
call because last suspending core will be ACPU0 in most of the case.

Now it may be possible that user may disable the ACPU0 using hot-plug
and after that it suspends Linux. So in that case ACPU0 will not be
last suspending core.

To overcome above scenario, pass the current running processor ID
while calling set_wakeup_source().
