arch/x86: Provide readXp/writeXp helpers in arch/mmio.h

These p-suffixed helpers allow dropping pointer casts in call-sites,
which is particularly useful when accessing registers at an offset from
a base address. Move existing helpers in chipset code to arch/mmio.h and
create the rest accordingly.
