drivers/spi/spi_flash: Add page_size to struct spi_flash
Add a new member page_size to spi_flash structure so that the various
spi flash drivers can store this info in spi_flash along with the
other sizes (sector size and total size) during flash probe. This
removes the need to have {driver}_spi_flash structure in every spi
flash driver.
This is part of patch series to clean up the SPI flash and SPI driver
interface.
