Re-reading the partition table doesn't work reliably, it fails if
anything on the device is still in use and it's not trivial to prevent
every possible case of a block device still being in use somehow.
Therefore, instead of relying on the in-kernel partition parser to know
where to write the configuration backup, use OpenWrt's format-agnostic
fwtool to strip off all metadata from the image and count its blocks
while writing. In that way we can know where to write the config backup
without needing the kernel to parse the MBR and FIT structures.

Add common features 'gpio', 'nand', 'pci', 'pcie', 'squashfs' and 'usb'
for all mediatek targets, add 'display' and 'usbgadget' for MT7623.
Sort features alphabetically while at it.

A full read-write rootfs cannot work inside uImage.FIT as the hash
will obviously change once writing to it. Disable generating ext4
rootfs images.

Update Kernel config and set Linux 5.10 for mediatek/mt7623.
(patches have already been updated to 5.10 when mt7622 was bumped)
Tested on Bananapi BPi-R2.

The supported MT7623 boards are mostly identical (what with being a
System-on-Chip and all), so unify the DEVICE_PACKAGES for them, and add
ext4 and usb support for them.
