When brya boards that use ChromeOS autoupdate update their firmware,
devices with SOC_INTEL_CSE_SUB_PART_UPDATE will end up attempting to
replace IOM and NPHY BPDT firmware in the CSE region. However, because
of the way the autoupdate works, the CSE RO will not be updated during
autoupdate. This means that these boards now have different stitching
schemes between CSE RO and RW and this causes the sub-partition update
to fail and the boot hangs. To remedy the situation for these boards,
a separate FMD files is provided so they can continue to use the
cse_serger tool for stitching. The only boards affected were kano and
brask, so they are updated here.
BUG=b:218376385

image with this patch and system boots.
