security/vboot: Add two weak methods for vboot2
In order to make VBOOT2 independent from the CHROMEOS
kconfig option a weak method for get_write_protect_state
and get_recovery_mode_switch() is required.
Introduce a kconfig option for controlling this
behaviour.
This is a temporary fix and will be removed afterwards.
