dmaengine: tegra: explicitly select DMA_VIRTUAL_CHANNELS
Enabling TEGRA186_GPC_DMA will cause this build failure unless some other
DMA driver which uses DMA_VIRTUAL_CHANNELS is enabled:
ERROR: modpost: "vchan_dma_desc_free_list" [drivers/dma/tegra186-gpc-dma.ko] undefined!
ERROR: modpost: "vchan_init" [drivers/dma/tegra186-gpc-dma.ko] undefined!

ERROR: modpost: "vchan_find_desc" [drivers/dma/tegra186-gpc-dma.ko] undefined!
make[1]: *** [scripts/Makefile.modpost:136: Module.symvers] Error 1
Add an explicit select of DMA_VIRTUAL_CHANNELS to avoid this.
