In cases where the client bus gets corrupted or if the end device
ceases to send/receive data, the DMA could wait for the data forever.
Tegra234 supports recovery of such channels hung in flush mode.
Add a separate compatible for Tegra234 so that this scenario can be
handled in the driver.
v3->v4:
* Updated binding doc to use enum for compatible instead of const
v2->v3:
* Updated binding docs and device tree compatible
v1->v2:
* split device tree change to a different patch.
* Update commit message
