[Intel-gfx] [PATCH v3 08/11] drm/i915: Move SNPS PHY registers to their own header

These registers are only needed in a couple files and on specific
platforms; let's keep them separate from the general register pool.
v2:
- Don't forget to include i915_reg_defs.h (Jani)
- Ensure include guard matches header name (Jani)
