[PATCH] dt-bindings: gpu: img,powervr-rogue: add spacemit,k1-gpu and spacemit,k3-gpu

[Baihui Liang <liangbaihui@linux.spacemit.com>]

Add compatible strings for the IMG GPUs in SpacemiT K1 and K3 SoCs:
- K1: IMG BXE-2-32 (adds a dedicated entry for a single core
  clock and power domain).
- K3: IMG BXM-4-64 (shares the same configuration and entry as
  the T-Head TH1520).

Both SoCs require a single power domain provided by the APMU driver
(currently pending mainline):
