Log Message:

arm: Use asm-defines.h for struct per_cpu members
Port the logic over from x86 and also drop CHECK_ASSUMPTION here.
The only slightly ugly detail: the PERCPU_SIZE_SHIFT define is now
duplicated in both asm/percpu.h instances because there is no good
generic header yet to hold it. Can be cleaned up later on.

arm: Disable maintenance interrupt on successful injection
We enable the maintenance interrupt when all list registers are in use.
However, there was no disabling of it again. Apparently, it rarely
triggered in the field, otherwise we would have seen a lot of
maintenance interrupt storms, thus locked-up systems.
This introduces another callback to enable or disable the maintenance
interrupt. It is now controlled by irqchip_inject_pending, the function
that is also called when handling a maintenance interrupt.

arm: Make sure to not queue interrupt that were rejected as duplicates
If the inject_irq callback detect that an interrupt is already queued
in some list register, do not insert it into the software queue, thus
coalesce the event like real hardware does.
The change in the return code of inject_irq is more cosmetic, to reflect
the meaning better.

arm: Convert software queue of pending interrupts into a ring
This massively simplifies the code and reduces the memory usage in

arm: Enable maintenance interrupt also from irqchip_set_pending
In case we set an interrupt pending for the local CPU and cannot queue
it with the hardware, make sure the maintenance interrupt is on.
Otherwise, we risk to delay guest interrupts or cause the guest to get
stuck.
