[ Upstream commita0e43bb997] Currently the Gen2 port in IPQ8074 will cause the system to hang as it accesses DBI registers in qcom_pcie_init_2_3_3(), and those are only accesible after phy_power_on(). Move the DBI read/writes to a new qcom_pcie_post_init_2_3_3(), which is executed after phy_power_on().

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.
