cbi: Add CONFIG_EEPROM_CBI_WP
This commit adds the config option, CONFIG_EEPROM_CBI_WP. It is to be
defined when the EC directly controls the CBI EEPROM WP signal. The EC
will set the WP according to the result of `system_is_locked()`. Note
that once the WP is set, the EC must be reset via EC_RST_ODL in order
for the WP to become unset. This is enabled by the accompanying
hardware.
