dt-bindings: pinctrl: qcom,msm8226: add functions and input-enable

The MSM8226 pinctrl driver supports input-enable, blsp_i2c4, blsp_uart4
and sdc3 functions and DTS already uses it:

  qcom-msm8226-samsung-s3ve3g.dtb: pinctrl@fd510000: 'blsp1-i2c1', 'blsp1-i2c2', 'blsp1-i2c3', 'blsp1-i2c4', 'blsp1-i2c5' ...
  qcom-apq8026-lg-lenok.dtb: pinctrl@fd510000: touch-state: 'oneOf' conditional failed, one must be fixed:
    'input-enable' does not match any of the regexes: 'pinctrl-[0-9]+'
