arm64: dts: qcom: msm8996-xiaomi: align PMIC GPIO pin configuration with DT schema

Bindings expect PMIC GPIO pin configuration nodes to be named with
'-state' suffix:

  qcom/msm8996-xiaomi-scorpio.dtb: pmic@0: gpio@c000: 'irled-default', 'keypad-default' do not match any of the regexes: '-state$', 'pinctrl-[0-9]+'

Drop also additional indentation via "pinconf" to make the code a bit
smaller.
