Subject: [PATCH] irqchip/qcom-pdc: Allow QCOM_PDC to be loadable as a permanent module

Allows qcom-pdc driver to be loaded as a permanent module.

An earlier version of this patch was merged in a larger patchset
but was reverted entirely when issues were found with other
drivers, so now that Marc has provided a better solution in his
Hybrid probing patch set, I wanted to re-submit this change.
