dt-bindings: mtd: nand: Document the generic rb-gpios property 



A few drivers use this property to describe GPIO pins used to sample
the NAND Ready/Busy state. Let's make it part of the generic binding
doc.

          Contains one or more GPIO descriptor (the numper of descriptor

          depends on the number of R/B pins exposed by the flash) for the

          should be set to GPIOD_ACTIVE_HIGH unless the signal is inverted.
