[edk2-platforms][PATCH V2 4/7] Platform/Sgi: Fix ACPI Low Power Idle states for RD-V1

["Pranav Madhu" <pranav.madhu@arm.com>]

RD-V1 platform supports only the platform co-ordinated LPI. So fix the
LPI Level ID value accordingly.

Additionally, as this platform does not support residency counter, clear
the residency counter frequency from _LPI object's control method.
