[PATCH v3 7/7] mtd: rawnand: ams-delta: use GPIO API for data I/O

Don't readw()/writew() data directly from/to GPIO port which is under control of gpio-omap driver, use GPIO API instead. Degrade of performance on Amstrad Delta is significant, can be recognized as a regression, that's why I'm still submitting this patch as RFC. The driver should work with any 8+
