board: ge: bx50v3: Enable hardware watchdog
Enable the hardware watchdog on bx50v3 to cause it to reset in the event
the board hangs.
Configure GPIO_9 pin as WDOG1_B so that a watchdog timeout results in a
full system reset.
The watchdog is used and reconfigured by systemd approximately 1.7 seconds
into boot. Adding a few seconds for U-Boot and a few more seconds as a
safety margin.
Note that the PCIe controller is _not_ put back into a safe state prior
to board reset. This is a problem if board reset is implemented as CPU
reset.
