boot/efi: factor out generic mmu functions

This change moves the common functions related to EFI memory map
to arch/generic for arm, arm64, x86.

riscv64 and x86_64 shall be handled separately as they use some
more architecture-specific logic:
* riscv64 needs special treatment for the M-mode resident code
located at 0x80000000 which is reported as available in the
EFI memory map provided by u-boot.
* x86_64 has a slightly different logic for building the
memory regions list so some additional rework and testing will be
needed before it can be unified with the generic mmu functions.

arm64: Reuse possible TTBR1 allocations only if we come from a valid EL1 context.

* This allows rPI3 reaching the kernel
* Handling & reporting this value helps understanding the behaviour of the different boot contexts
* As long as more real HW platforms are being ported, reusing this value needs to be reevaluated
