John Schock 748bea7171 ArmPkg: ArmPsciResetSystemLib: PSCI warm reset fix ...

The current warm reset implementation attempts the PSCI SYSTEM_RESET2
command twice without clearing the local variable used for Arg1. This can
result in passing a random value as the reset type, which may cause the
PSCI call to behave unexpectedly and fall back to a cold reset.

This change addresses the issue by:
- Correcting the monitor call function ID.
- Explicitly zeroing the reset type field before invoking the PSCI
interface.

The updated warm reset flow has been tested and confirmed to invoke
SYSTEM_RESET2 as expected.
