drm/i915/skl: Structure/enum definitions for SKL clocks
Adding structure/enum for SKL clocking implementation.
v2: Addressed Damien's comment
- Removed internal structure from this header file
v3: Stove this into the generic intel_dpll_id enum and give them the established
DPLL_ID_ prefixes. (Daniel)
v4: - We'll only try to share DPLL1/2/3, leaving DPLL0 to eDP
- Use SKL in the skylake shared DPLL names
- Re-add the skl_dpll enum
(Damien)
v5: Remove SKL_DPLL_NONE (Daniel)
v6: Modified as per review comments from Paulo
