drm/i915: expose _SUBSLICE_MASK GETPARM
Assuming a uniform mask across all slices, this enables userspace to determine the specific sub slices can be enabled. This information is required, for example, to be able to analyse some OA counter reports where the counter configuration depends on the HW sub slice configuration.
