security/vboot: Remove selected_region from struct vboot_working_data
Since we already have pre-RAM cache for FMAP (CB:36657), calling
load_firmware() multiple times is no longer a problem. This patch
replaces vboot_get_selected_region() usage with vboot_locate_firmware(),
which locates the firmware by reading from the CBMEM cache.
In addition, returning false from vboot_is_slot_selected() implies the
recovery path was requested, i.e., vb2_shared_data.recovery_reason was
set. Therefore, we simply remove the vboot_is_slot_selected() check from
vboot_check_recovery_request().
