Shawn Lin d43b47a114 PCI: rockchip: dw: Reset device before enabling power 
To more precisely follow the spec, we should make sure
refclk is available and stable for device only after
stable training. In previous way, if the refclk is provided
by external chip, enabling power means refclk is ready before
anything, and then we reset the device to hope the chip back
to the initial state. But we find some devices are not really
meant to do that, that being said, the spec is vague here so
we can't make any promise from the vendor that #PERST will take
everything back.

Move resetting device before enabling power to restrictly follow
the spec, no matter whether #PERST is work or not, we just rely
on the power control.

Fixes: c84a4aa411 ("PCI: rockchip: dw: Move deassert #PERST after enabling LTSSM")

README 

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
