gpu: ion: omap: add apis to register and export ion buffers from a pvr fd
Exporting omap_ion_register_pvr_export through ion. This is needed since
PVR is built as a module as the abstraction uses an exported function
pointer.
omap_ion_share_fd_to_buffers api is added which retrieves the ion handles
from the pvr fd and calls ion_share on the ion handles to return the
shared buffers. The requestor can then call ion_import using its own ion
client to get its own ion handles.
Note that this functionality is intended to be reworked majorly as part of
gralloc's migration to dma buf functionality in new ION framework.
