drivers/spi/spi_flash: organize spi flash by sector topology
By grouping the spi flash parts by their {vendor, sector topology} tuple one can use a common probe function for looking up the part instead of having per-vendor probe functions. Additionally, by grouping by the command set one can save more space as well. SST is the exception that requires after_probe() function to unlock the parts. 2KiB of savings in each of verstage, romstage, and ramstage on Aleena Chrome OS Build.
