arm64: dts: qcom: sc8180x: modernize MDSS device definition

Follow the lead of other platforms and update DT description of the MDSS
device:

- Use generic node names (dislpay-subsystem, display-controller, phy)
  instead of the platform-specific ones (mdss, mdp, dsi-phy)
- Add platform-specific compatible string to DSI controllers.
