arm/arm64: target-efi prep

This series mostly prepares kvm-unit-tests/arm for targeting EFI
platforms. The actually EFI support will come in another series,
but these patches are good for removing assumptions from our memory
maps and about our PSCI conduit, even if we never merge EFI support.

arm/arm64: mmu: Stop mapping an assumed IO region

By providing a proper ioremap function, we can just rely on devices
calling it for each region they need (as they already do) instead of
mapping a big assumed I/O range. We don't require the MMU to be
enabled at the time of the ioremap. In that case, we add the mapping
to the identity map anyway. This allows us to call setup_vm after
io_init. Why don't we just call setup_vm before io_init, I hear you
ask? Well, that's because tests like sieve want to start with the MMU
off, later call setup_vm, and all the while have working I/O. Some
unit tests are just really demanding...

While at it, ensure we map the I/O regions with XN (execute never),
as suggested by Alexandru Elisei.

lib: arm64: Add missing ISB in flush_tlb_page

Linux commit d0b7a302d58a made it abundantly clear that certain CPU
implementations require an ISB after a DSB. Add the missing ISB to
flush_tlb_page. No changes are required for flush_tlb_all, as the function
already had the ISB.

arm: make pgtable.h private to mmu.c

The pgd/pmd/pud definitions are not needed outside the architecture-
dependent MMU functions. In fact, it probably would be simpler to
have completely different files for 32-bit and 64-bit ARM. However,
as a first and possibly less controversial step, hide them inside
that file.

Implement asm_mmu_enable and flush_tlb_all, and then make a final
