ArmPkg/BdsLib: Removed PSCI discoverability from the Linux loader

Some platforms might decide to not support PSCI in their FDT-aware Linux
system even if their firmware supports it.
It is the responsibility of the platform engineer to provide the appropriate FDT.

The PCD gArmTokenSpaceGuid.PcdArmPsciSupport is not required anymore.
