PCI: qcom-ep: Add Qualcomm PCIe Endpoint controller driver
Add driver for Qualcomm PCIe Endpoint controller based on the DesignWare
core with added Qualcomm-specific wrapper around the core. The driver
support is very basic such that it supports only enumeration, PCIe
read/write, and MSI. There is no ASPM and PM support for now but these will
be added later.
The driver is capable of using the PERST# and WAKE# side-band GPIOs for
operation and written on top of the DWC PCI framework.
[bhelgaas: wrap a few long lines]
Co-developed-by: Siddartha Mohanadoss <smohanad@codeaurora.org>
[mani: restructured the driver and fixed several bugs for upstream]
