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.
