Refactor SuperIO accesses
We had duplicated code under different names and even open-coded some
functions in some places.
wbsio_read/regval -> sio_read wbsio_write/regwrite -> sio_write
wbsio_mask -> sio_mask
board_biostar_p4m80_m4 now uses existing IT87 functions.
Corresponding to flashrom svn r547.
