mtd: spi-nor: Add a RWW flag
Introduce a new (no SFDP) flag for the feature that we are about to
support: Read While Write. This means, if the chip has several banks and
supports RWW, once a page of data to write has been transferred into the
chip's internal SRAM, another read operation happening on a different
bank can be performed during the tPROG delay.
