xfree86: Inline xf86{Read,Write}Mmio{8,16,32} on alpha

Browse Source 
In commit 9db2af6f75 (xfree86: Remove xf86{Map,Unmap}VidMem) we
somehow stopped exporting xf86{Read,Write}Mmio{8,16,32}. Since the
function pointer indirection was intended to support dense vs sparse and
sparse support is now gone, we can just make the functions static inline
in compiler.h and avoid all of this.
