José Roberto de Souza 6056517ab8 drm/i915/tgl: Guard and warn if more than one eDP panel is present
On TGL+ it's possible to have PSR1 enabled in other ports besides DDIA.
PSR2 is still limited to DDIA. However currently we handle only one
instance of PSR struct. Lets guard intel_psr_init_dpcd() against
multiple eDP panels and warn about it.

v2: Reword commit message to be TGL+ only and with the info where
PSR1/PSR2 are supported (Lucas)

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.
