[00/11] PCI: aardvark controller changes BATCH 6

Hello Lorenzo,

here is continuation of Aardvark patches.

Some patches come from those not applied in batch 5, and were rebased.

Patches 1 and 2 touch the pciehp driver. We have changed commit
messages, since originally we thought the patches are also needed
to fix a bug, but this turns out not to be true [1].

Patch 3 was changed to also select the hotplug support in Kconfig.

Patch 7 (suspend support) was changed to use new macro
NOIRQ_SYSTEM_SLEEP_PM_OPS, and also changed commit message.

Patches 8-11 are new.
