dmaengine: dw-axi-dmac: Add blank line after function

checkpatch.pl reports a CHECK warning in dw-axi-dmac-platform.c:

  CHECK: Please use a blank line after function/struct/union/enum
  declarations
  drivers/dma/dw-axi-dmac/dw-axi-dmac-platform.c:

The Linux kernel coding style [Documentation/process/coding-style.rst]
requires a blank line after function definitions to provide visual
separation between distinct code elements.

This patch inserts the required blank line after the closing brace of the
function definition after dw_axi_dma_set_byte_halfword(), placing it
before the contextual comment that describes the locking requirements.
