[PATCH v2 2/2] arm64: tegra: Enable DMA Support on Tegra194 QSPI

[Aaron Kling via B4 Relay <devnull+webgeek1234.gmail.com@kernel.org>]

From: Aaron Kling <webgeek1234@gmail.com>

Without dma enabled pio mode is used and flash storage such as the one
on the p3668 module times out and cannot complete any transfers. In some
cases, these timeouts cause hangs and cbb faults.
