dmaengine: dw: dmamux: Fix build without CONFIG_OF
When built without OF support, of_match_node() expands to NULL, which
produces the following output:
>> drivers/dma/dw/rzn1-dmamux.c:105:34: warning: unused variable 'rzn1_dmac_match' [-Wunused-const-variable]
static const struct of_device_id rzn1_dmac_match[] = {
One way to silence the warning is to enclose the structure definition
with an #ifdef CONFIG_OF/#endif block.
