pinctrl: qcom: Add flexibility to disable the wakeup capability 



By default, the system firmware enables the mpm wakeup functionality
of all the supported GPIOs. However, certain usecases demand that
this capability be disabled on certain gpios. Hence, provide a
generic interface to disable the GPIOs as needed.
