SDM845's Adreno SMMU is unique in that it actually advertizes support
for 16K (and 32M) pages, which doesn't hold for newer SoCs.

This however, seems either broken in the hardware implementation, the
hypervisor middleware that abstracts the SMMU, or there's a bug in the
Linux kernel somewhere down the line that nobody managed to track down.

Applied to will (for-joerg/arm-smmu/updates), thanks!
