Anshuman Khandual 38e4b6605e arm64/mm: Drop ARM64_KERNEL_USES_PMD_MAPS
Currently ARM64_KERNEL_USES_PMD_MAPS is an unnecessary abstraction. Kernel
mapping at PMD (aka huge page aka block) level, is only applicable with 4K
base page, which makes it 2MB aligned, a necessary requirement for linear
mapping and physical memory start address. This can be easily achieved by
directly checking against base page size itself. This drops off the macro
ARM64_KERNE_USES_PMD_MAPS which is redundant.
