[PATCH 3/3] drm/panel: Add display_timing entry for the HannStar HSD070PWW1 panel

The HannStar HSD070PWW1 LVDS panel data sheet lists allowed ranges additionally
to the typical values for pixel clock rate (64.3 MHz ... 82 MHz) and blanking
intervals (54 to 681 clocks horizontally, 3 to 23 lines vertically).
This patch replaces this panels' drm_display_mode entry with a display_timing
entry to describe acceptable timings.
Since the HSYNC/VSYNC are unused, the distribution between front porches, back
porches, and sync pulse lengths was chosen at will.
