ArmPlatformPkg/PrePeiCore: permit entry with the MMU enabled
Some platforms may set up a preliminary ID map in flash and enter EFI
with the MMU and caches enabled, as this removes a lot of the complexity
around cache coherency. Let's take this into account, and avoid touching
the MMU controls or perform cache invalidation when the MMU is enabled
at entry.
