The dtbs_check reports that the 'dma-coherent' property is "unevaluated
and invalid" for the host1x@13e00000 device on Tegra194 and Tegra234
platforms. Fix this by updating the dt-binding document for host1x to
add the 'dma-coherent' property for these devices.
Fixes: 361238cdc525 ("arm64: tegra: Mark host1x as dma-coherent on Tegra194/234")
