Mark Salter 7511f28792 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_tx_submit" [drivers/dma/tegra186-gpc-dma.ko] undefined!
  ERROR: modpost: "vchan_tx_desc_free" [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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
