[PATCH 5/5 v2] arm/mmu: Use memblock_first_region_size() helper

[Alexander Kuleshov]

The 0a11142e commit (mm/memblock: Introduce memblock_first_region_size()
helper) introduced memblock_first_region_size() helper for the getting
size of the first memblock region. Let's use it instead of directly access
to structure.
