ARM: dts: imx7d-pico: Add watchdog support

imx7d-pico has the WDOG1_B pin connected to the PMIC, so add the wdog1 node and use the 'fsl,ext-reset-output' property to properly describe it.

Currently the following eMMC error is seen:

mmc1: mmc_select_hs200 failed, error -74

On imx7d-pico the eMMC VCCQ is fixed at 3.15V, so pass the 'no-1-8-v' property to properly describe that 1.8V operation is not possible.

Applied both, thanks.

Hi Shawn,

Maybe you forgot to push them to your tree?

Hmm, it's been on imx/dt for quite a few days, and for-next needs to be updated though.
