OMAPDSS: DSSCOMP: export needed functions for PVR SGX

OMAPDSS: DSSCOMP: export needed functions for PVR SGX

Make dsscomp symbol visible to kernel modules. The SGX DDK
in modular form requires this symbol to be exported.

OMAPDSS: DSSCOMP: Remove PVR_SGX dependency.

OMAPDSS: DSSCOMP: Remove PVR_SGX dependency.

In order to disable the in-kernel version of the DDK
and be able to use it as a module we need to remove
this dependency.
No harm to DSSCOMP, it will just wait until a DDK
is installed to execute.

OMAPDSS: drop small YUV encoded frames on OMAP44xx

OMAPDSS: drop small YUV encoded frames on OMAP44xx

OMAP44xx has hardware limitation: in stall mode, when the frame pixel size
is less than output SyncFifo depth(16), DISPC hangs without sending any data.
Simple workaround is to drop such frame, as cases when YUV frames of this size
are very rare.
