drm/i915: Manage HSW/BDW LCPLLs with the shared dpll interface
Manage the LCPLLs used with DisplayPort, so that all the HSW/BDW DPLLs
are managed by the shared dpll code.
v2: Introduce INTEL_DPLL_ALWAYS_ON flag to please state checker. (Ander)
v3: Initialize pll->flags in intel_shared_dpll_init(). (Ander)
