media: ti: vpe: Re-introduce multi-instance and multi-client support

Browse source

vpdma_update_dma_addr() was originally added to support multi-instance and
multi-client in vpdma. However it was dropped as it was unused.

We are adding support for TI VIP. Some devices may have multiple VIP
instances each with its own VPDMA engine. Within VIP, two slices can use a
single VPDMA engine simultaneously. So support for multi instances and
multiple clients is needed. Hence reintroduce multi-instance and
multi-client support. Also add kernel doc and switch to GPL version of
EXPORT_SYMBOL.

This reverts commit 9314891df1.
