Make workaround for errata i870 applicable in Host mode as
well(previously it was enabled only for EP mode) as per errata
documentation: http://www.ti.com/lit/er/sprz450/sprz450.pdf
Driver will continue to work with w/o applying errata in host mode when
using older DT, to maintain backward compatibility.

Tested on DRA72 EVM

Changes since v4:
Fail driver probe if DT binding is absent for EP(as it is in current
code)

Changes since v3:
Rebase onto latest next
Drop DT patches from this series. They will be sent separately once
driver changes in this series is merged.

Changes since v2:
Reorder patch 2 to appear at the last.
Collect all the ACKs

Changes since v1:
Drop IRQ handling rework (will be sent out separately)


Vignesh R (2):
  dt-bindings: PCI: dra7xx: Add bindings for unaligned access in host
    mode
  pci: dwc: pci-dra7xx: Enable errata i870 for both EP and RC mode
