Subject: [PATCH] dmaengine: ti: omap-dma: Drop of_match_ptr to fix -Wunused-const-variable

The of_device_id is included unconditionally by of.h header and used
in the driver as well.  Remove of_match_ptr to fix W=1 compile test
warning with !CONFIG_OF:

    drivers/dma/ti/omap-dma.c:1892:34: warning: 'omap_dma_match' defined but not used [-Wunused-const-variable=]
     1892 | static const struct of_device_id omap_dma_match[] = {
