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.
