ARM: OMAP2+: add omapdss_init_of()
The OMAP display architecture requires a bunch of platform devices which
are not created via .dts (for now). We also need to pass a few function
pointers and the DSS hardware version from the arch code to omapdss
driver.
This patch adds omapdss_init_of() function, called from board-generic at
init time, which handles those tasks.
