ARM: OMAP: dma: Make use of cpu_class_is_omap2() to avoid future patching.
cpu_class_is_omap2() contains all OMAP2+ devices. So update the DMA code cpu checks accordingly so that there is no need to patch the file for any future OMAP2+ devices. In long run, all these attributes should come from hwmod dev_attr based on DMA IP version. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>
