aic79xx.h:

Browse Source 
Add a 7901A specific feature definition.

aic79xx_pci.c:
	Split out the general aic790X setup into it's own
	setup handler that works on single and dual controllers.
	Adjust all other PCI setup handlers to initialize the
	chips basic features and type before calling the generic
	handler.

	Turn off a few Rev B workarounds that are not required
	on the 7901B.
