doc/Host-tools-overview: tiffs-mkfs description updated
The first version of tiffs-mkfs did not include a journal file in the created
FFS, expecting the firmware to create it on first boot. All historical
firmwares prior to a recent FC fix (2020-05) contain a bug in that code path,
thus images made with the first version of tiffs-mkfs were only acceptable to
very recent FC firmwares. tiffs-mkfs has now been extended to include an empty
journal in the created FFS, thus the restriction of working with recent fw only
has been lifted.
