drivers/spi/spi_flash.c: Add SPI vendor IDs

Currently SPI vendor IDs are magic numbers in spi_flash.c. These definitions
are needed for AMD's fch_spi. So add the definitions to spi_generic.h and use
it at spi_flash.c

BUG=b:136595978
TEST=Build test of several platforms that don't use stoneyridge. Build and boot
grunt (using stoneyridge new fch_spi).
