From: Randolph Sapp <redacted> Add the relevant device tree node for Imagination's BXS-4-64 GPU. These devices uses a similar MSMC configuration to the J721S2. As such, they also require the use of the dma-coherent attribute.

Following https://lore.kernel.org/linux-arm-kernel/DBE4UO2RGAYX.17V1DAF8MQYJM@kernel.org/ (local) Is it worth having ti,j784s4-gpu here? Are there any SoC specific quirks that driver will need to handle?
