Kevin O'Connor 8977c4e764 rp2040: Fix watchdog enable
The rp2040 watchdog does not actually reset anything by default.  The
psm_hw->wdsel field must be programmed to actually get a reset on a
watchdog failure.  Program that field so the watchdog is usable.

Also, disable the watchdog before attempting a reboot into the
bootloader.  Otherwise the machine may just reboot a second time due
to a missed watchdog event in the bootloader.
