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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
