[PATCH] ARM: dts: imx: ventana: add alternate PWM4 pinmux for GW54xx

[Tim Harvey]

The GW54xx can provide PWM4 out either the off-board backlight connector
or the off-board digital I/O connector. By default the pinmux routes it
to the backlight connector but this pinctl alternate provides documentation
for those who may want to change it.
