drm/hisilicon: Add crtc driver for ADE

Add crtc funcs and helper funcs for ADE.

v8: None.
v7:
- A few Regs define clean up and typo fixs.
v6:
- Cleanup reg-names dt parsing.
v5:
- Use syscon to access ADE media NOC QoS registers instread of directly
  writing registers.
- Use reset controller to reset ADE instead of directly writing registers.
v4: None.
v3:
- Make ade as the master driver.
- Use port to connect with encoder.
- A few cleanup.
v2:
- Remove abtraction layer.
