From: Pankaj Bansal <pankaj.bansal at nxp.com>
Add ArmPlatformLib for LX2160ARDB platform that is based on
ArmPlatformPkg/Library/ArmPlatformLibNull.
Apart from the the interfaces exposed by ArmPlatformLibNull, this
library also implements gPlatformGetClockPpi, which is specific to NXP
SOCs' based platforms.
Refer edk2-platforms/Silicon/NXP/Include/Ppi/NxpPlatformGetClock.h for
the details.

Notes:
V2:
- New commit
- split Platform/NXP/LX2160aRdbPkg/Library/ArmPlatformLib/ in two parts
part containing gPlatformGetClockPpi is put before PL011UartClockLib
implementation.
