This patch is a drm driver for Starfive Soc JH7110,
I am sending Drm driver part and HDMI driver part.

We used GEM framework for buffer management,
and for buffer allocation,we use DMA APIs.

the Starfive HDMI servers as interface between a LCD Controller 
and a HDMI bus. 
A HDMI TX consists of one HDMI transmitter controller 
and one HDMI transmitter PHY.
(Sound support is not include in this patch)

This patchset should be applied on next branch.

V1:
Changes since v1:
- Further standardize the yaml file.
- Dts naming convention improved.
- Fix the problem of compiling and loading ko files.
- Use drm new api to automatically manage resources.
- Drop vs_crtc_funcs&vs_plane_funcs, subdivide the plane's help interface.
- Reduce the modifiers unused.
- Optimize the hdmi driver code

V2:
Changes since v2:
- fix the error about checking the yaml file.
- match drm driver GEM DMA API.
- Delete the custom crtc property .
- hdmi use drmm_ new api to automatically manage resources.
- update the modifiers comments.
- enabling KASAN, fix the error during removing module 

V3:
Changes since v3:
- Delete the custom plane property.
- Delete the custom fourcc modifiers.
- Adjust the calculation mode of hdmi pixclock.
- Add match data for dc8200 driver.
- Adjust some magic values.
- Add a simple encoder for dsi output.
