Riana Tauro bc417e54e2 drm/xe: Enable configfs support for survivability mode ...

Enable survivability mode if supported and configfs attribute is set.
Enabling survivability mode manually is useful in cases where pcode does
not detect failure, validation and for IFR (in-field-repair).

To set configfs survivability mode attribute for a device

echo 1 > /sys/kernel/config/xe/0000:03:00.0/survivability_mode

The card enters survivability mode if supported

v2: add a log if survivability mode is enabled for unsupported
    platforms (Rodrigo)
