arm64: dts: qcom: sc8280xp: align TLMM pin configuration with DT schema

DT schema expects TLMM pin configuration nodes to be named with
'-state' suffix and their optional children with '-pins' suffix.

  qcom/sc8280xp-crd.dtb: pinctrl@f100000: kybd-default-state: 'oneOf' conditional failed, one must be fixed:
    'pins' is a required property
    'function' is a required property
    'disable', 'int-n', 'reset' do not match any of the regexes: 'pinctrl-[0-9]+'
    'disable', 'int-n', 'reset' do not match any of the regexes: '-pins$', 'pinctrl-[0-9]+'
