OMAPDSS: don't use dss bus in suspend/resume
We have support functions to suspend and resume all the displays that are used with system suspend. These functions use the dss bus to iterate the display devices. As we aim to remove the custom dss bus totally, this patch removes the explicit use of dss bus from these functions. Instead the for_each_dss_dev() macro is used to go through the devices.
