drivers/spi/spi_flash: remove spi flash names
The names of each spi flash cause quite a bit of bloat in the text
size of each stage/program. Remove the name entirely from spi flash
in order to reduce overhead. In order to pack space as closely as
possible the previous 32-bit id and mask were split into 2 16-bit
ids and masks.
On Chrome OS build of Aleena there's a savings of >2.21KiB in each
of verstage, romstage, and ramstage.
