[PATCH 00/18] PCI: aardvark controller changes BATCH 5

[Marek Behún]

Hello Lorenzo, Krzysztof,

here comes batch 5 of changes for Aardvark PCIe controller.

This batch
- adds support for AER
- adds support for DLLSC and hotplug interrupt
- adds support for sending slot power limit message
- adds enabling/disabling PCIe clock
- adds suspend support
- optimizes link training by adding it into separate worker
- optimizes GPIO resetting by asserting it only if it wasn't asserted
  already
