Don't init pcode and restore VRAM objects in vain. We can rely on primary GT GUC_STATUS to detect whether card has really lost power even when d3cold is allowed by xe. Adding d3cold.lost_power flag to avoid pcode init and vram restoration. Also cleaning up the TODO code comment. v2: - %s/xe_guc_has_lost_power()/xe_guc_in_reset(). - Used existing gt instead of new variable. [Rodrigo] - Added kernel-doc function comment. [Rodrigo] - xe_guc_in_reset() return true if failed to get fw.

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.
