[PATCH v2 00/18] PCIe support for DRA7xx

[Kishon Vijay Abraham I]

This patch series adds support for PCIe in DRA7xx including drivers and dt
data. PCIe in DRA7xx uses desingware IP and hence this re-uses the
pcie desingware driver (pcie-designware.c) by Jingoo.

The last couple of patches are marked as *TEMP* since the TI reset driver [1]
is not yet merged and is in RFC.

Tested broadcom PCIe card and XIO2000 bridge along with DGE530T ethernet
card.

Changes from v1:
* removed external clock support fro APLL since the clock framework patches
  are still in RFC.
* The configuration address space should be given in *reg* and made the
  corresponding driver changes in pcie-designware.c
* Used untraslated address while programming ATU since that is needed for
  DRA7. With this PCIe should be made the child node of axi.
* Used a new irq domain for PCIe legacy interrupts.
* Added clocks and dt data for the second instance of PCIe controller (with
  status = disabled).

Changes from RFC:
* Added external clock support for PCIE APLL
* Miscellaneous cleanups in Documentation, macro naming etc..
