drm/i915: Dump more configuration information for DSI

Browse Source 
Dump out more of the DSI configuration details during init.
This includes pclk, burst_mode_ratio, lane_count, pixel_overlap,
video_mode_format and reset_timer_val.

v2: Dump more info (Chris)
v3: Use the VIDEO_MODE_ defines for consistency (Chris)
    Dump dphy_reg too (Chris)
