drm/i915/dpll: Accept intel_display as argument for shared_dpll_init

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.
Initialize dpio_phy and dpio_channel since with IS_GEMINILAKE()
and IS_BROXTON() compiler knows it will return false for xe but
since display->platform.xx is a runtime check which means the
compiler sees a potential path where uninitialized variables
could be accessed and raises a warning.

initialized [Jani]
