Subject: [PATCH V2 0/2] Add support to handle prefetchable memory

This patch series adds support for configuring the DesignWare IP's ATU
region for prefetchable memory translations.
It first starts by flagging a warning if the size of non-prefetchable
aperture goes beyond 32-bit as PCIe spec doesn't allow it.
And then adds required support for programming the ATU to handle higher
(i.e. >4GB) sizes.

V2:
* Dropped third patch from the series as Rob's patch
  (commit: 9fff3256f93d PCI: dwc: Restore ATU memory resource setup to use last entry)
  is already accepted
* Rebased first two patches on top of Rob's latest patch
