Hi Thomas, Andrew, Ilpo et al.,

This is the last round of updates for armada-370-xp irqchip before
I send the one patch adding support for SoC Error interrupts.

Again, most of the patches should be easy to review, with the possible
exception of patches 6/13 and 8/13: these convert the driver to use
driver private structure for its intenral state. I split this
conversion into 3 patches in hopes that it will be easier to review.

Patch 10/13 is a fix of an issue I discovered that has been present
since 2017.

This series can be applied on tip/irq/core, but only after rounds 2, 3
and 4 are applied first:
