fmap: Reduce RO_SECTION size to exclude RO_VPD area.
RO_SECTION is used for calculating a fixed "firmware hash" and also for firmware
updating (for early testing devices and protos), so it should not include RO_VPD
(which may be different for each device, and must be preserved when being
updated).
The region for all "write-protected" area is WP_RO, which contains both
RO_SECTION and WP_RO.
