lib: Add Kconfig option to enable/disable auto fallback control
Under certain conditions, e.g. automated testing, it is useful to have the payload (e.g. Linux) reset the reboot_bits CMOS value. This allows automated recovery in the case of coreboot starting properly but the payload failing to start due to bad configuration data provided by the coreboot image under test.
