[PATCH 5/6] dt-bindings: cpufreq: move Mediatek cpufreq dt-bindings document to proper place

From: Sean Wang <sean.wang at mediatek.com>
The old place is Documentation/devicetree/bindings/clock/ that would
let people hard to find how to use Mediatek cpufreq driver, so moving
it to the new place as other cpufreq dirvers are done would be better.

-Device Tree Clock bindins for CPU DVFS of Mediatek MT8173 SoC
-
-Required properties:
-- clocks: A list of phandle + clock-specifier pairs for the clocks listed in clock names.
-- clock-names: Should contain the following:
- "cpu" - The multiplexer for clock input of CPU cluster.
- "intermediate" - A parent of "cpu" clock which is used as "intermediate" clock
- source (usually MAINPLL) when the original CPU PLL is under
- transition and not stable yet.
- Please refer to Documentation/devicetree/bindings/clk/clock-bindings.txt for
- generic clock consumer properties.
-- proc-supply: Regulator for Vproc of CPU cluster.
-
-Optional properties:
-- sram-supply: Regulator for Vsram of CPU cluster. When present, the cpufreq driver
- needs to do "voltage tracking" to step by step scale up/down Vproc and
- Vsram to fit SoC specific needs. When absent, the voltage scaling
- flow is handled by hardware, hence no software "voltage tracking" is
- needed.
