pinctrl: qcom: disable GPIO groups with no pins
pinctrl-msm only accepts an array of GPIOs from 0 to n-1, and it expects
each group to support have only one pin (npins == 1).
We can support "sparse" GPIO maps if we allow for some groups to have zero
pins (npins == 0). These pins are "hidden" from the rest of the driver
and gpiolib.
Access to unavailable GPIOs is blocked via a request callback. If the
requested GPIO is unavailable, -EACCES is returned, which prevents
further access to that GPIO.
