ARM: HYP/non-sec: enable ARMV7_LPAE if HYP mode is supported

Browse Source 
ARMV7_LPAE is required in order to enable the MMU in HYP mode.
And we really want to enable the MMU in HYP mode such that we can
enable the the caches.  Otherwise U-Boot code (such as the EFI
implementation) that runs in HYP mode will run at a snils pace.

Say Y here to use the long descriptor page table format. This is
