drm/panfrost: Force AARCH64_4K page table format on MediaTek MT8192

MediaTek MT8192 SoC has an ARM Mali-G57 MC5 GPU (Valhall-JM). Now that
Panfrost supports AARCH64_4K page table format, let's enable it on this
SoC.

Running glmark2-es2-drm [0] benchmark, reported the same performance
score on both modes Mali LPAE (LEGACY) vs. AARCH64_4K, before and after
this commit. Tested on a Mediatek (MT8395) Genio 1200 EVK board.
