[PATCH v5 1/9] drm/hisilicon/hibmc: Add hisilicon hibmc drm master driver

[zourongrong@gmail.com (Rongrong Zou)]

Add DRM master driver for Hisilicon Hibmc SoC which used for
Out-of-band management. Blow is the general hardware connection,
both the Hibmc and the host CPU are on the same mother board.

+----------+       +----------+
|          | PCIe  |  Hibmc   |
|host CPU( |<----->| display  |
|arm64,x86)|       |subsystem |
+----------+       +----------+
