irqchip/qcom-pdc: Switch to IRQCHIP_PLATFORM_DRIVER and allow as a module

This patch revives changes from Saravana Kannan to switch the
qcom-pdc driver to use IRQCHIP_PLATFORM_DRIVER helper macros,
and allows qcom-pdc driver to be loaded as a permanent module.

Earlier attempts at this ran into trouble with loading
dependencies, but with Saravana's fw_devlink=on set by default
now we should avoid those.

[jstultz: Folded in with my changes to allow the driver to be
 loadable as a permenent module]
