This commit updates the OpenWrt-based U-Boot for this device, allowing
to boot a FIT firmware image stored in an SD card.
The environment has been updated accordingly to allow for managing images
on the two different supported firmware boot media configurations
(NOR or SDMMC).
Erasing the U-Boot environment when upgrading is recommended, so that
the correct DTS overlay is applied.
New behaviour
-------------
The default environment "bootconf" variable is set to
config-1#mt7981b-gatonetworks-gdsp-gps
rendering the GPS module accessible.
You may set it to something like
config-1#mt7981b-gatonetworks-gdsp-sd
to be able to use the MMC controller.
To boot from a firmware image stored in an SD card, you may set the
bootmedia environment variable:
# fw_setenv bootmedia sd
and reboot.
Should the bootmedia variable be absent or it's content not recognized
as valid (e.g., does not contain "nor" or "sd"), NOR boot will be
attempted.

Some patches have been manually rebased to match the upstream
changes. This patch also fixes the dtc warning for reserved-memory
dts node. If #address-cells and #size-cells are not same as the
root node definitions, the dtc will complain about it.
All defconfigs are refreshed by `make "$board"_defconfig` and
`make savedefconfig`.

The GatoNetworks GDSP is a re-branded version of the R5000 5G Industrial
router from Yinghua Technologies.
Advantages over stock bootloader:
1. supports serving the external GPIO WDT, allowing for easier work in U-Boot
shell
2. supports cool features like netconsole, easy recovery, scripting and so on
3. allows using FIT image and image integrity validation
and ultimately gives you much more flexibility to implement your tweaks.
Known issues
------------
To make it easier to operate the device, console I/O multiplexing support has
been enabled in U-Boot configuration. Setting I/O related U-Boot environment
variables to something like "serial,nc" will have the desired effect. Still,
setting these variables to such a value in the persistent environment will
lead to a crash and make it impossible to boot the system or recover it. I
decided to leave it on anyway since I think it can be very practical in
development.
