Marc Zyngier 93a68acc49 irqchip/gic: Correctly validate OF quirk descriptors ...

[ Upstream commit 91539341a3b6e9c868024a4292455dae36e6f58c ]

When checking for OF quirks, make sure either 'compatible' or 'property'
is set, and give up otherwise.

This avoids non-OF quirks being randomly applied as they don't have any
of the OF data that need checking.
