The extension module is connected to the system I2C bus. Before the
module is powered, it can pull the lines low, preventing I2C access to
the board descriptor.

NEO-M9 modems sometimes boot into Safe Boot mode because of the 3.3 V
power sequencing defined by the PMIC.
Change SPL/U-Boot to
- insert LDO feeding GNSS modem in automatic power sequencing
- reset GNSS module at power on reset.

With kernel upgrade to 5.10 the paths of all nodees have changed because
of the way the ti drivers are handled.
These paths must therefore be adaped in u-boot in order to stay
compatible.
This means that u-boot versions before this commit are not 100%
compatible with kernel 5.10, but they should usually be able to boot.
Also after this change, older kernel will not work 100% but should still
boot.

With the introduction of the SSF watchdog feature a get and then a
set of the PMIC's CONTROL_D register leads to an activation of the
watchdog and causes a watchdog reset at the time the kernel is
being decompressed.
Currently we disable the watchdog from the bootloader and activate
it only in user space.

- check rs232 for break condition duration to invoke
factory reset or recovery boot. same logic as reset button.
- check rs232 break condition followed by command
- 'f': factory reset
- 'r': recovery boot
This makes it possible to boot normaly with disconnected uart line.
Previously the system booted into recovery in that case.

allow invoking factory reset and recovery boot via:
- uart break, followed by command ('r', 'f')
- using uart rxd as reset line

in rare cases the default automatic mode switching can disable a power
rail. To prevent this all used buck regulators are configured to
synchronous mode.
- fill out /user_module node with:
- status: okay/disabled
- model: UM type
- hw version/revision
- network configuration
- show product variant in boot log
- set product variant in device tree /model
- create new 'um' module to handle user module detection
- in nmhw21 board file
- try to read presence register and check for magic ID
- if found, determine type and hw version
- display information at startup

- apply sequencer fixes up to and including v1.2 config
- note: v1.3 config is incorrectly stored as v1.2 and will thus
also be "fixed", although this is not required.

phy addresses have been changed from rev 1.0 (6+7) to rev 2.0 and later
(2+3). the function ft_eth() overwrites these addresses in fdt_path just
for rev 1.0 boards.
