[PATCH 1/5] drm/xe: Keep all defaults in single header

[Michal Wajdeczko <michal.wajdeczko@intel.com>]

We already have most of Xe defaults defined in xe_module.c,
where we use them for the modparam initializations, but some
were defined elsewhere, which breaks the consistency.

Introduce xe_defaults.h file, that will act as a placeholder
for all our default values, and can be used from other places.
