Looks like quite a few omaps have sharp ls037v7dw01 that's configured as various panel dpi entries for whatever legacy reasons. For device tree based support, let's just configure these properly for panel ls037v7dw01 instead of panel dpi. This patch creates a common file for panel ls037v7dw01, and makes boards ldp and omap3-evm to use it. The panel for ldp is configured in the qvga mode and omap3-evm panel in vga mode. The ls037v7dw01 also seems to be coupled with an ad7846 touchscreen controller for the omaps, so let's add a basic configuration for the touchscreen also using the default values. Note that we can now remove the regulator-name = "vdds_dsi" entry for ldp, that's no longer needed as we have the entry for vdds_dsi-supply = <&vpll2>.
