[coreboot] [PATCH] flashrom: Fix all remaining bustypes (no more NONSPI in flashchips.c)

[Urja Rannikko]

Fix all NONSPI bustypes in flashchips.c.
Also noted as a comment if an FWH/LPC chip supports A/A Mux mode.

I think we should add a bit in bustypes for A/A Mux so an external
programmer can use it if available, any objections?

I'll do it if its ok, should it be CHIP_BUSTYPE_AAMUX ? (or _A_A_MUX?)
(or _PPMODE?)
