The DMA subsystem could be entirely disabled in Kconfig and then the
TEGRA20_APB_DMA option isn't available too. Hence kernel configuration
fails if DMADEVICES Kconfig option is disabled due to the unsatisfiable
dependency.

The FUSE driver isn't a critical driver and currently it only provides
NVMEM interface to userspace which isn't known to be widely used, and
thus, it's fine if FUSE driver fails to load.

Let's remove the erroneous Kconfig dependency and let the FUSE driver to
fail the probing if DMA is unavailable.
