drivers/mrc_cache: Make bootstate for SPI writes variable
The default time for writing MRC data to flash is at the exit of
BS_DEV_ENUMERATE but this is too early for some implementations.
Add an option to Kconfig for allowing a late option to be selected.
The timing of the late option is at the entry of BS_OS_RESUME_CHECK.
TEST=Select option and inspect console log on Kahlee
