vboot: Change VbExEc implementations to support RO update
This change will be used to support EC-RO software sync by allowing for
access to the readonly region of firmware. Currently only the writable
section is accessed by vboot using VB_SELECT_FIRMWARE_A and B.
TEST=built on jerry and check that the RO hash can be read and the image
can be updated.
