Add device binding documentation for the PDC Interrupt controller on
QCOM SoC's like the SDM845. The interrupt-controller can be used to
sense edge low interrupts and wakeup interrupts when the GIC is
non-operational.

+PDC interrupt controller
+
+Qualcomm Technologies Inc. SoCs based on the RPM Hardened archicture have a
+Power Domain Controller (PDC) that is on always-on domain. In addition to
+providing power control for the power domains, the hardware also has an
+interrupt controller that can be used to help detect edge low interrupts as
+well detect interrupts when the GIC is non-operational.
+
+GIC is parent interrupt controller at the highest level. Platform interrupt
+controller PDC is next in hierarchy, followed by others.

This driver only configures the interrupts, does not handle them.

Not sure if the above statement belongs to the binding.

Will fix.

Thanks,
Lina
