[PATCH] ide: AU1200 IDE update 



Changes here include removing all of CONFIG_PM while it is being repeatedly
smacked with a lead pipe, moving the BURSTMODE param to a #define (it should
be defined almost always anyway), fixing the rqsize stuff, pulling ide_ioreg_t,
and general cleanups and whatnot.
