OMAP: omap4sdp: move display init from board file to dss-common.c
Device tree support for omapdss is still some way in the future. In an effort to get a minimal DSS support for DT enabled kernel on selected OMAP4 boards, we'll go for a temporary solution: We will call the same non-DT omapdss setup code for OMAP4 SDP and Pandaboards from board-generic.c, thus enabling DSS for those boards. This patch moves the display setup code from board-4430sdp.c to dss-common.c. dss-common.c will be called by the board-4430sdp.c when running on non-DT kernel, and by board-generic.c when running on DT enabled kernel.
