vboot: fix CBFS MCACHE on zork

Three things are fixed in this patch:

* Call vboot_run_logic instead of verstage_main in psp_verstage.
vboot_run_logic will handle RW mcache build by calling after_verstage.

* replace cbfs low-level apis to cbfs_map
cbfs_map will handle RO mcache build.

* call update_boot_region before save_buffers
This will make RO mcache to be transferred to x86.
