dmaengine: Remove dma_request_slave_channel_compat() wrapper

At its original introduction, dma_request_slave_channel_compat() used a
wrapper, to accommodate filter functions that modify the mask passed.
Filter functions can no longer modify masks, and the mask parameter was
made const in commit a53e28da574a40bc ("dma: Make the 'mask' parameter
of __dma_request_channel const") consecutively.

Hence remove the wrapper, and rename __dma_request_slave_channel_compat()
to dma_request_slave_channel_compat(), to get rid of one more function
name starting with a double underscore.
