[RFC 10/10] arm64/mm: Enable CONFIG_ARM64_PA_BITS_52 on CONFIG_ARM64_[4K|16K]_PAGES

[Anshuman Khandual]

All required FEAT_LPA2 components for 52 bit PA range are already in place.
Just enable CONFIG_ARM64_PA_BITS_52 on 4K and 16K pages which would select
CONFIG_ARM64_PA_BITS_52_LPA2 activating 52 bit PA range via FEAT_LPA2.
