dmaengine: dw-axi-dmac: Remove unnecessary return statement from void function

Browse Source 
checkpatch.pl --strict reports a WARNING in dw-axi-dmac-platform.c:

  WARNING: void function return statements are not generally useful
  FILE: drivers/dma/dw-axi-dmac/dw-axi-dmac-platform.c

According to Linux kernel coding style [Documentation/process/
coding-style.rst], explicit "return;" statements at the end of void
functions are redundant and should be omitted. The function will
automatically return upon reaching the closing brace, so the extra
statement adds unnecessary clutter without functional benefit.

This patch removes the superfluous "return;" statement in
dw_axi_dma_set_hw_channel() to comply with kernel coding standards and
eliminate the checkpatch warning.
