drivers/spi: provide option to not include all flash drivers 

All flash drivers are automatically included in the build unless
COMMON_CBFS_SPI_WRAPPER was selected. However, there are cases
where these drivers are unnecessary such as certain intel platforms
where spi controller uses hardware sequencing without any ability
to manually probe the device. Therefore, provide an option that the
SoC can set the default value for. The COMMON_CBFS_SPI_WRAPPER
option is still honored by not including all drivers when that
is selected.
