[PATCH] drm/i915: HDMI audio gets the TMDS clock by crtc_clock

[PATCH] drm/i915: HDMI audio gets the TMDS clock by crtc_clock

[libin.yang]

From: Libin Yang <libin.yang@linux.intel.com>

HDMI audio should use crtc_clock to get the TMDS clock.

Besides, this patch renames mode to adjusted_mode to unify the name.
