TIMEPULSE is internally connected with SAFEBOOT_N
in the GNSS modem. The pulldown pulls the signal so
low, that in some cases the modem starts in bootloader
mode.
Also remove pull ups from UART to avoid cross currents
at powerup.
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.
- enable extension module power already in SPL

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
