The omapdrm platform device is unused, as a replacement is now
registered in the omapdss driver. Remove it.

The omapdss_find_dss_of_node() function isn't used outside of its
compilation unit, make it static.

The omap_display_init() is implemented in the mach-omap2/display.c so the
declaration should have been there as well.
Change the board files to include display.h to avoid build breakage at the
same time.

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.

Move omap_vout device creation inside the omap_display_init so that we can
correctly create the device based on the presence of omapdss within the
platform.
For example, on a kernel image supporting multiple platforms, omap_init_vout
will create a omapdrm platform device on a AM33xx platform even though it
doesn't have a DSS block.

omap_display_init
Move omapfb and omapvrfb device creation inside the omap_display_init so that
we can correctly create the device based on the presence of omapdss within the
platform.
For example, on a kernel image supporting multiple platforms, omap_init_vrfb and
omap_init_fb will create omapvrfb and omapfb platform devices respectively on a
AM33xx platform even though it doesn't have a VRFB or DSS block.

bootloader
Resetting DISPC when a DISPC output is enabled causes the DSS to go into an
inconsistent state. Thus if the bootloader has enabled a display, the hwmod code
cannot reset the DISPC module just like that, but the outputs need to be
disabled first.
Add function dispc_disable_outputs() which disables all active overlay manager
and ensure all frame transfers are completed.
Modify omap_dss_reset() to call this function and clear DSS_CONTROL,
DSS_SDI_CONTROL and DSS_PLL_CONTROL so that DSS is in a clean state when the
DSS2 driver starts.
This resolves the hang issue(caused by a L3 error during boot) seen on the
beagle board C3, which has a factory bootloader that enables display. The issue
is resolved with this patch.
Thanks to Tomi and Sricharan for some additional testing.
