arm64: dts: ti: k3-j722s: fix pinctrl settings

It appears that pinctrl-single is misused on this SoC to control both
the mux and the input and output and bias settings. This results in
non-working pinctrl configurations for GPIOs within the device tree.

This is what happens:
 (1) During startup the pinctrl settings are applied according to the
     device tree. I.e. the pin is configured as output and with
     pull-ups enabled.
 (2) During startup a device driver requests a GPIO.
 (3) pinctrl-single is applying the default GPIO setting according to
     the pinctrl-single,gpio-range property.

This would work as expected if the pinctrl-single is only controlling
the function mux, but it also controls the input/output buffer enable,
the pull-up and pull-down settings etc (pinctrl-single,function-mask
covers the entire pad setting instead of just the mux field).

Remove the pinctrl-single,gpio-range property, so that no settings are
applied during a gpio_request() call.
