mediatek: mt7622: bpi-r64: rewrite MMC uImage.FIT sysupgrade
Similar to mt7623, also no longer use 'blockdev' and stop relying on
in-kernel partition parsers. Instead, strip off all metadata using
'fwtool' while writing the firmware image and scrape the number of
blocks written from 'dd', then use that block offset to stash the
configuration backup.
