drivers/spi/spi_flash: introduce common spi_flash_part_id object
To further drive to a common approach for describing the spi flash parts in the drivers add spi_flash_part_id object. All the drivers are updated to utilize the new object. Additionally, the driver_private is also not needed in the spi_flash object. A Chrome OS build of Aleena provides 960 byte saving of text. A subsequent patch will save more memory.
