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.
