Subject: [PATCH 2/8] drm: bridge: dw_hdmi: Use passed mode instead of stored previous_mode

Use the passed mode instead of mixing use of passed mode and the stored
previous_mode. The passed mode is currenly always the previous_mode.

Also fix a small type and add a variable to help shorten a code line.
