Update the architecture dependency to be the generic Tegra
because the driver works on the four latest Tegra generations
not just T210, if you build a kernel with a specific
ARCH_TEGRA_xxx_SOC option that excludes 210 you don't get
this driver.
Fixes: 433de642a7
("dmaengine: tegra210-adma: add support for Tegra186/Tegra194")

DMA engines can do asynchronous data transfers without

involving the host CPU. Currently, this framework can be

used to offload memory copies in the network stack and

RAID operations in the MD driver. This menu only presents

DMA Device drivers supported by the configured arch, it may
