Chipset: remove sis630 chipset enable for sis540

Browse Source 
SiS630 chipset enable is equal to sis540 plus superio "poking".

Superio poking equals IT8705F flash write enable, which is currently
dealt with on a board by board basis in board_enable.c. Not all
630 and newer based boards come with it8705/sis950 superios.

Corresponding to flashrom svn r794.
