ARM: dts: axp803/axp81x: Drop GPIO LDO pinctrl nodes 

The "ldo-io0" and "ldo-io1" regulators are enabled/disabled by toggling
the pinmux between two functions. This happens in the regulator driver.
Setting the pinmux to "ldo" in the DT is inappropriate because it would
enable the regulator before the driver has a chance to set the correct
initial voltage.
