drm/i915/cx0: Drop Cx0 crtc_state from HDMI TMDS pll divider calculation

Drop crtc_state from HDMI TMDS calculation and replace with the
parameters that are only required. Follow-up changes will call
these functions without a crtc_state available.

v2: Keep required crtc_state param for intel_c20_pll_tables_get()
    and other functions calling this one.
