Subject: [PATCH v2 03/17] dt-bindings: clock: Convert marvell,mmp2-clock to json-schema

Convert the fixed-factor-clock binding to DT schema format using
json-schema.

While at that, fix a couple of small errors: make the file base name
match the compatible string, add an example and document the reg-names
property.

-* Marvell MMP2 Clock Controller
-
-The MMP2 clock subsystem generates and supplies clock to various
-controllers within the MMP2 SoC.
-
-Required Properties:
-
-- compatible: should be one of the following.
-  - "marvell,mmp2-clock" - controller compatible with MMP2 SoC.
-
-- reg: physical base address of the clock subsystem and length of memory mapped
-  region. There are 3 places in SOC has clock control logic:
-  "mpmu", "apmu", "apbc". So three reg spaces need to be defined.
-
-- #clock-cells: should be 1.
-- #reset-cells: should be 1.
-
-Each clock is assigned an identifier and client nodes use this identifier
-to specify the clock which they consume.
-
-All these identifiers could be found in <dt-bindings/clock/marvell,mmp2.h>.
