drm/panel: simple: Add support for Giantplus GPG482739QS5 



This patch adds support for the GiantPlus GPG48273QS5 4.3" WQVGA TFT LCD
panel to the simple-panel driver.

This panel is connected via a parallel bus and uses both HSYNC and
VSYNC, whose lengths are unfortunately not clearly defined. The
datasheet only specifies the front- and backporch length, but the timing
diagram suggests that both sync signals should be asserted for exactly
one clock cycle.
