Once RMA open is processed and CCD state is updated, the AP still
might require to perform some operations, even if TPM is not available
any more.
With this patch enable_ccd_factory_mode() does not trigger device
reset, if invoked by the RMA open handler.
Another modification is that WP is disabled immediately when factory
mode is enabled, there is no need to reset the H1 for WP status to
change.
BRANCH=cr50, cr50-mp
BUG=b:115495431
TEST=verified that running 'gsctool -a -r <authcode>' sets to 'Y' all
CCD properties, disables write protection, but does not reboot
the device.

Cr50 branches did not cherry pick the patch which introduced the
SYSTEM_IMAGE_RW_A enum, let's use SYSTEM_IMAGE_RW instead as the rest
of Cr50 code does.

The factory reset command can be used to enable ccd factory mode. The
command can open ccd if write protect is removed and ccd hasn't been
restricted. Right now we check FWMP and the ccd password before allowing
factory reset. Factory reset cannot be used to get around anything that
disables ccd.
This adds 72 bytes.
BUG=b:77543904
BRANCH=cr50
TEST=Try enabling factory mode using factory reset. Verify setting write
protect, setting the FWMP disable ccd bit, or setting a ccd password
prevents factory reset from enabling factory mode.

We have determined the checks to run for board_is_first_factory_boot.
This change updates cr50 to check for those conditions and enable ccd
when the system determines that it is first boot in the factory. This
will check that the board id is erased and the inactive image is a GUC
image.
The factory updates Cr50 from the GUC image, because those GUC images
don't have support for everything they need to do in the factory. To
determine that cr50 just recovered from that factory update, it will
check that the GUC image is still in the inactive region and no board id
is set.
There are 2 images installed in GUC 0.0.13 and 0.0.22, so cr50 will
check these versions. Future GUC images will have a field in the header
declaring that they are a GUC image. I still need to create the GUC
field in the header and check that in inactive_image_is_guc_image.
Factory mode can't be enabled on deep sleep resume. It is only enabled
after power-on reset or hard reset.
This change also moves factory stuff into a factory_mode file instead of
keeping it in board.c
This adds 200 bytes.
BUG=b:77543904
BRANCH=cr50
TEST=Verify factory mode is only enabled when cr50 recovered from
reboot not deep sleep resume, 0.0.13 or 0.0.22 are in the inactive
region, and the board id is erased.
