Add specific compatible string to document the GPU SMMU present on
Nord SoC, and constrain it to the single HLOS vote clock.
Signed-off-by: Shawn Guo <shengchao.guo@oss.qualcomm.com>

Changes for v2:
- Add the missing HLOS vote clock constraint
- Link to v1: https://lore.kernel.org/all/20260901140816.74200-1-shengchao.guo@oss.qualcomm.com/
