dt-bindings: pinctrl: qcom,sc8280xp-lpass-lpi: add input-enable and bias-bus-hold

Allow bias-bus-hold and input-enable properties (already used in
SC8280XP LPASS LPI nodes):

  sa8540p-ride.dtb: pinctrl@33c0000: tx-swr-default-state: 'oneOf' conditional failed, one must be fixed:
    'pins' is a required property
    'function' is a required property
    'clk-pins', 'data-pins' do not match any of the regexes: 'pinctrl-[0-9]+'
    'bias-bus-hold' does not match any of the regexes: 'pinctrl-[0-9]+'
