EFS: Add support for early firmware selection
Chromebox ECs performs EFS: verifying firmware before the AP boots.
This patch updates host commands which are required for the EFS.
The change includes:
* Update EC_CMD_FLASH_REGION_INFO to accept EC_FLASH_REGION_UPDATE
* Update EC_CMD_VBOOT_HASH to accept EC_VBOOT_HASH_OFFSET_UPDATE
When EC_FLASHS_REGION_UPDATE is specified, EC_CMD_FLASH_REGION_INFO
returns the slot which currently is not hosting a running RW copy.
When EC_VBOOT_HASH_OFFSET_UPDATE is specified, EC_CMD_VBOOT_HASH
computs the hash of the update slot. This hash covers the entire
region, including the signature at the end.
This patch undefines CONFIG_CMD_USBMUX and CONFIG_CMD_TYPEC
for gru to create space.
