arm64: io: Use asm-generic high level MMIO accessors

Browse source

Remove custom arm64 MMIO accessors read{b,w,l,q} and their relaxed
versions in support to use asm-generic defined accessors. Also define
one set of IO barriers (ar/bw version) used by asm-generic code to
override the arm64 specific variants.
