drm/i915/bxt: Fix HDMI DPLL configuration
a277ca7dc01d should've been a no-functional-change commit, but it
removed the initialization of the dpll_hw_state for HDMI outputs,
resulting in state mismatches and a failed modeset with blank
screen. Fix this by reinstating the dpll_hw_state initialization.
v2:
- Make bxt_ddi_hdmi_set_dpll_hw_state() static.
