drm/i915: Replace tmds_clock_speed and link_rate with just ls_clock
There's no need to distinguish between the DP link rate and HDMI TMDS clock for the purposes of the LPE audio. Both are actually the same thing more or less, which is the link symbol clock. So let's just call the thing ls_clock and simplify the code.
