From: Senthilvadivu Guruswamy <svadivu@xxxxxx>
Hwmod adaptation design requires each of the DSS HW IP to be a platform driver.
Platform driver of dsshw has to be registered before of dispc, rfbi, dsi1,
venc and omapdisplay driver should be after all the HW IPs. Sequence it with
arch_initcall and device_initcall_sync.
