Update the img,powervr-rogue.yaml to include the T-HEAD TH1520 SoC's
specific GPU compatible string.
The thead,th1520-gpu compatible, along with its full chain
img,img-bxm-4-64, and img,img-rogue, is added to the
list of recognized GPU types.
While the BXM-4-64 GPU IP is designed with two distinct power domains,
the TH1520 SoC integrates it with only a single, unified power gate that
is controllable by the kernel.
The binding enforces this with a specific if block for the
thead,th1520-gpu compatible that requires a single power-domains entry
and disallows power-domain-names.
The B-series GPU rule is also updated to include img,img-bxm-4-64
and to explicitly exclude the TH1520.
