Add WinBond Super IO helpers.
* These helpers severely clear up winbond superio usage.
* Removed board_iwill_dk8_htx as it can be replaced by
board_agami_aruma (Mondrian Nuessle).
* Renamed board_agami_aruma to w83627hf_gpio24_raise.
* Clarified comments in w83627hf_gpio24_raise, and added
some things from the old iwill code.
* Moved all board functions name argument to const.
(warning breaks build)
* Moved iwill entry in board_pciid_enables.
