mfd: cpcap: convert documentation to schema and add

Merge series from Svyatoslav Ryhel <clamor95@gmail.com>:

The initial goal was only to add support for the CPCAP used in the Mot
Tegra20 board; however, since the documentation was already partially
converted, I decided to complete the conversion to schema too.

-Motorola CPCAP PMIC voltage regulators
-------------------------------------
-
-Requires node properties:
-- "compatible" value one of:
-    "motorola,cpcap-regulator"
-    "motorola,mapphone-cpcap-regulator"
-    "motorola,xoom-cpcap-regulator"
-
-Required regulator properties:
-- "regulator-name"
-- "regulator-enable-ramp-delay"
-- "regulator-min-microvolt"
-- "regulator-max-microvolt"
-
-Optional regulator properties:
-- "regulator-boot-on"
-
-See Documentation/devicetree/bindings/regulator/regulator.txt
-for more details about the regulator properties.
-
-Example:
-
-cpcap_regulator: regulator {
-	compatible = "motorola,cpcap-regulator";
-
-	cpcap_regulators: regulators {
-		sw5: SW5 {
-			regulator-min-microvolt = <5050000>;
-			regulator-max-microvolt = <5050000>;
-			regulator-enable-ramp-delay = <50000>;
-			regulator-boot-on;
-		};
-	};
-};
