[PATCH 3/4] ARM: dts: sti: extract display subsystem out of soc

Thu Jul 17 12:15:34 PDT 2025
The display subsystem represent how IPs are interacting together and
have nothing to do within the SoC node.
Extract it from the SoC node and let IPs nodes in the Soc node.
Several nodes did not use conventional name:
* sti-display-subsystem -> display-subsystem
* sti-controller -> display-controller
* sti-tvout -> encoder
* sti-hda -> analog
* sti-hqvdp -> plane
