pinctrl: qcom: Register functions before enabling pinctrl

pinctrl consumers can request states while the pinctrl core enables the
controller. On Qualcomm pinctrl drivers this can happen before the SoC
function list has been registered, which leaves the function table
incomplete during state lookup.

On APQ8064 this can fail while claiming pinctrl hogs:

   apq8064-pinctrl 800000.pinctrl: invalid function ps_hold in map table
   apq8064-pinctrl 800000.pinctrl: error claiming hogs: -22
   apq8064-pinctrl 800000.pinctrl: could not claim hogs: -22

Register Qualcomm pinctrl with devm_pinctrl_register_and_init(), add the
SoC pin functions, and only then enable the pinctrl device.
