Adds a device ID to ramtron_initialize, which is stored in the ramtron_dev_s structure.
This ID is used when calling SPI_SELECT to board specific logic to allow chip select on the SPI bus.
This change is NOT backwards compatible, as it changes the function signature of ramtron_initialize.
This implementation is based on the handling of chip select in nuttx/drivers/mtd/sst26.c:sst26_initialize_spi().
Additional Changes:
- Add MB85RS64V to ramtron supported parts list.
