Instead of making all SPI drivers allocate space for a spi_flash
structure and fill it in, udpate the API to allow callers to pass in a
spi_flash structure that can be filled by the flash drivers as
required. This also cleans up the interface so that the callers can
maintain and free the space for spi_flash structure as required.
