ArmPkg: Move ARM Platform drivers from ArmPkg/Drivers/ to ArmPlatformPkg/Drivers/

Browse Source 
The idea is to keep ArmPkg responsible for the ARM architectural modules and ArmPlatformPkg
the ARM development platform packages (with their respective drivers).


ArmPlatformPkg: Reduce driver dependency on ArmPlatform.h

- Move some driver definitions from C-Macro to PCD values
- Unify PCD driver namespace
