[PATCH 6/6] OMAPDSS: APPLY: Remove display dependency from overlay and manager checks

[Archit Taneja <archit@ti.com>]

In order to check the validity of overlay and manager info, there was a need to
use the omap_dss_device struct to get the panel resolution. manager_info now
contains the manager size(which should be the panel resolution in most cases).
Hence, we don't need to depend on the display resolution.

manager_info is now passed to dss_ovl_check() to see if the overlay fits within
the manager area.
