dma: omap: hide legacy interface
The legacy interface for omap-dma is only used on OMAP1, and the
same is true for the non-DT case. Make both of these conditional on
CONFIG_ARCH_OMAP1 being set to simplify the dependency.
The non-OMAP stub functions in include/linux/omap-dma.h are note needed
any more either now, because they are only called on OMAP1.
