[PATCH 8/9] drm/i915/dpll: Accept intel_display as argument for shared_dpll_init

[Suraj Kandpal <suraj.kandpal@intel.com>]

Use intel_display as an argument for intel_shared_dpll_init() and
replace drm_i915_private in function wherever possible.
While at it prefer using display->platform.xx over IS_PLATFORM.
