vmbase: Abstract CPU arch in write_volatile_u8()
Move write_volatile_u8() to the arch-agnostic import vmbase::arch, using
cfg_if to conditionally select the body of the function. Future
functions moved to this submodule will follow the same pattern, allowing
client code (including the rest of this crate) to become arch agnostic.
Test: m pvmfw_bin
