José Roberto de Souza 93bf76ed88 drm/i915/psr: Handle PSR errors
Sink will interrupt source when it have any PSR error.
DP_PSR_VSC_SDP_UNCORRECTABLE_ERROR is a PSR2 but already
handling it here.
The only missing error to be handled is DP_PSR_LINK_CRC_ERROR that
will be taken in care in a futher patch.

v6:
not handling DP_PSR_LINK_CRC_ERROR here

v5:
handling all PSR errors here, so the commit message and
comment have changed

v3:
disabling PSR instead of exiting on error

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.
