[PATCH 00/17] 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 RFC:
* Added external clock support for PCIE APLL
* Miscellaneous cleanups in Documentation, macro naming etc..
