ArmPlatformPkg/NorFlashDxe: Move NorFlash driver from ArmVExpressPkg to ArmPlatformPkg

This NOR Flash driver can be reused for other platform (eg: ARM Realview EB).

To make this driver reusable on other platforms the NorFlashPlatformLib library
has been created to abstract the platform specific bits such as the pre-requirements
steps to the initialization and the geometry of the NOR Flash regions.
