ARM: hotplug cpu: ensure that __enable_mmu is identity mapped
__enable_mmu is required to be executed in an identity mapped region
to ensure that variances in CPUs do not cause a crash. We currently
achieve this by assuming that it will be co-located with
__create_page_tables. With hotplug CPU support, this assumption
becomes invalid. Implement a better solution which ensures that
it will be appropriately mapped no matter where it is placed.
