[PATCH V2 04/16] imx: imx8mm_beacon: enable pinctrl_wdog in SPL

[Peng Fan (OSS)]

From: Peng Fan <peng.fan at nxp.com>

Mark pinctrl_wdog as u-boot,dm-spl to clean up board code,

The set_wdog_reset() function is not necessary as this is handled by
the imx_watchdog.c driver due to the 'fsl,ext-reset-output' property
being set.
