[PATCH] soc/tegra: fix unmet dependency on DMADEVICES for TEGRA20_APB_DMA

[Julian Braha]

When SOC_TEGRA_FUSE is selected, and DMADEVICES
is not selected, Kbuild gives the following warning:

WARNING: unmet direct dependencies detected for TEGRA20_APB_DMA
  Depends on [n]: DMADEVICES [=n] && (ARCH_TEGRA [=y] || COMPILE_TEST [=y])
  Selected by [y]:
  - SOC_TEGRA_FUSE [=y] && ARCH_TEGRA [=y] && ARCH_TEGRA_2x_SOC [=y]

This is because SOC_TEGRA_FUSE selects TEGRA20_APB_DMA
without selecting or depending on DMADEVICES, despite
TEGRA20_APB_DMA depending on SOC_TEGRA_FUSE.

This unmet dependency bug was found by Kismet,
a static analysis tool for Kconfig. Please advise
if this is not the appropriate solution.
