dt-bindings: arm: fsl: Move DCFG and SCFG bindings to their own docs
In preparation to convert board-level bindings to json-schema, move various misc SoC bindings out to their own file. Acked-by: Shawn Guo <shawnguo@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: devicetree@vger.kernel.org Signed-off-by: Rob Herring <robh@kernel.org>

+Freescale DCFG
+
+DCFG is the device configuration unit, that provides general purpose
+configuration and status for the device. Such as setting the secondary
+core start address and release the secondary core from holdoff and startup.
+
+Required properties:
+ - compatible: Should contain a chip-specific compatible string,
+ Chip-specific strings are of the form "fsl,<chip>-dcfg",
+ The following <chip>s are known to be supported:
+ ls1012a, ls1021a, ls1043a, ls1046a, ls2080a.
+
+ - reg : should contain base address and length of DCFG memory-mapped registers
+
+Example:
+ dcfg: dcfg@1ee0000 {
+ compatible = "fsl,ls1021a-dcfg";
+ reg = <0x0 0x1ee0000 0x0 0x10000>;
+ };
