To support sparse GPIO maps, pinctrl-msm client drivers can specify
that a given GPIO has a pin count of zero.  These GPIOs will be
considered "hidden".  Any attempt to claim the GPIO will fail, and they
will not be listed in debugfs.

During a kexec shutdown, machine_kexec_mask_interrupts() will attempt
to disable all IRQs, even those that aren't enabled.  This includes
GPIOs that are unavailable (npins == 0), so add a check to the irq mask
and unmask functions.

I'm waiting for Bj?rn's review of the two remaining patches.

Bj?rn, do you have time to review these patches?  I'm hoping to get them 
into 4.14.
