[PATCH v4] PCI: add a new directory for designware core

From: Kishon Vijay Abraham I
Date: Thu Jan 05 2017 - 09:41:06 EST

group all the PCI drivers that use designware core in dwc directory.
dwc IP is capable of operating in both host mode and device mode and
keeping it inside the *host* directory is misleading. This is in
preparation for adding endpoint mode support in dwc driver.

Changes from v3:
*) Moved pci-keystone.h to dwc directory which was missed earlier

Changes from v2:
*) update MAINTAINERS file

Changes from v1:
*) instead of renaming *host* directory to *controller* directory,
move all the dwc drivers to dwc/ directory.
Next Steps:
Split pcie-designware.c to core, host-only and endpoint-only files.
