watchdog: imxwd: register explicit warm reset handler

With fsl,ext-reset-output and WDOG_B muxed correctly, the i.MX watchdog
will toggle an external signal to effect a PMIC reset.

That's good for normal use, but when exchanging information with the
BootROM over GPRs, a warm reset is required. This is needed e.g. to
set the reboot mode. Support this by defining a second, lower
priority, reset that will never toggle external lines.
