Marc Zyngier c579caef7c irqchip/gic-v4.1: Properly lock VPEs when doing a directLPI invalidation 
[ Upstream commit 926846a703 ]

We normally rely on the irq_to_cpuid_[un]lock() primitives to make
sure nothing will change col->idx while performing a LPI invalidation.

However, these primitives do not cover VPE doorbells, and we have
some open-coded locking for that. Unfortunately, this locking is
pretty bogus.

Instead, extend the above primitives to cover VPE doorbells and
convert the whole thing to it.

Fixes: f3a059219b ("irqchip/gic-v4.1: Ensure mutual exclusion between vPE affinity change and RD access")
