ArmPlatformPkg/ArmPlatformLib: Renamed ArmPlatformInitialize into ArmPlatformSecInitialize

Some platforms require some of their controllers to be initialized in Secure world.
This function make the difference between Secure and Normal world platform initialization.


ArmPlatformPkg/ArmPlatformLib: Introduce ArmPlatformNormalInitialize

Contain the code that initializes platform controllers that would be initialized in Normal World
by PlatformPei.
