drm/i915/display: Cleanup mplla/mpllb selection
The function intel_c20_use_mplla() is not really widely used and can be replaced with the more suitable pll->tx[0] & C20_PHY_USE_MPLLB expression. Let's remove the intel_c20_use_mplla() alltogether and replace mplla/mpllb selection by checking mpllb bit.
