MLK-12060 media: output: pxp_v4l2: Add filter function for dma_request_channel

Without the filter function, the dma_request_channel() API could possibly get
a sdma channel. The dma_request_channel() API does not return error but the
consequent operations on that channel will be invalid then the upper level
application expects to be stuck.

The patch added the filter functions to get right dma channel for the fix.
