The static inlines wrappers does not provide any value, and could be replaced by
direct calls to memcpy_fromio(), memcpy_toio(), memset_io().

If you decide to keep the wrappers I will not hold you back, so the

Reviewed-by: Sam Ravnborg <sam@ravnborg.org>

But I prefer the direct calls without the wrappers....
