drm/i915/gt: Create gt/gtN/.defaults/ for per gt sysfs defaults
Create a gt/gtN/.defaults/ directory (similar to
engine/<engine-name>/.defaults/) to expose default parameter values for
each gt in sysfs. This allows userspace to restore default parameter values
after they have changed. The empty 'struct gt_defaults' will be populated
by subsequent patches.
v2: Changed 'struct intel_rps_defaults rps_defaults' to
'struct gt_defaults defaults' (Andi)
