[PATCH v4 07/10] dt-bindings: soc: rockchip: Convert grf.txt to YAML

[cl]

From: Liang Chen <cl@xxxxxxxxxxxxxx>

Current dts files with 'grf' nodes are manually verified. In order to
automate this process grf.txt has to be converted to YAML.

Add new descriptions for:
"rockchip,rk3568-grf", "syscon", "simple-mfd"
"rockchip,rk3568-pmugrf", "syscon", "simple-mfd"

Signed-off-by: Liang Chen <cl@xxxxxxxxxxxxxx>

-* Rockchip General Register Files (GRF)
-
-The general register file will be used to do static set by software, which
-is composed of many registers for system control.
-
-From RK3368 SoCs, the GRF is divided into two sections,
-- GRF, used for general non-secure system,
-- SGRF, used for general secure system,
-- PMUGRF, used for always on system
-
-On RK3328 SoCs, the GRF adds a section for USB2PHYGRF,
-
-ON RK3308 SoC, the GRF is divided into four sections:
-- GRF, used for general non-secure system,
-- SGRF, used for general secure system,
-- DETECTGRF, used for audio codec system,
-- COREGRF, used for pvtm,
-
-Required Properties:
-
