mtd: rawnand: sunxi: Remove support for GPIO-based Ready/Busy polling
None of the existing platforms connect the R/B pin to a GPIO (they all use one of the dedicated R/B pin). Anyway, if we ever get short of native R/B pins, it's probably better to fallback to STATUS reg polling than trying to poll a GPIO.
