arm64: Document why spin_lock/unlock have memory barrier semantics
This makes it clearer why we have no explicit memory barrier in the
spin_lock/unlock implementation, in contrast to the ARMv7 version.
Based on research by Peng Fan.

arm-common: Fix barrier usage in irqchip_set_pending / irqchip_inject_pending
We were missing memory barriers before updating the lockless ring buffer
of pending interrupts, both on producer and consumer side. At the same
time, we can remove a barrier that is already provided implicitly by
spin_unlock on ARM.

arm/arm64: Populate memory_load_barrier
This abstraction is currently used for mmio region updates. There is no
reason why it could be left empty on ARM. Linux does not do that as
well.
What Linux also does is to map a write barrier on ishst. However,
Jailhouse has no abstraction for write-only barriers, thus cannot use
this mapping for its generic memory_barrier.
