Krait Documentation conversion

Convert kpss-acc driver Documentation to yaml.
The original Documentation was wrong all along. Fix it while we are converting it.
The example was wrong as kpss-acc-v2 should only expose the regs but we don't have any driver that expose additional clocks. The kpss-acc driver is only specific to v1. For this exact reason, limit all the additional bindings (clocks, clock-names, clock-output-names and #clock-cells) to v1 and also flag that these bindings should NOT be used for v2.

Running 'make dtbs_check' with the schema in this patch gives the following warnings. Consider if they are expected or the schema is incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check. This will change in the future.

Rework kpss-gcc driver Documentation to yaml Documentation. The current kpss-gcc Documentation have major problems and can't be converted directly. Introduce various changes to the original Documentation.

Add #clock-cells additional binding as this clock outputs a static clk named acpu_l2_aux with supported compatible.
Only some compatible require and outputs a clock, for the others, set only the reg as a required binding to correctly export the kpss-gcc registers. As the reg is shared also add the required syscon compatible.

I suppose this chunk is not so correct. We can not describe these properties as required since current DTs do not have them. Also if somebody decides to fix the mdm9615 or msm8660 platforms, he works have to change this (again). Thus I'd just leave this whole chunk out.

Rework kpss-gcc driver Documentation to yaml Documentation.

The current kpss-gcc Documentation have major problems and can't be converted directly. Introduce various changes to the original Documentation.

Add #clock-cells additional binding as this clock outputs a static clk named acpu_l2_aux with supported compatible.
Only some compatible require and outputs a clock, for the others, set only the reg as a required binding to correctly export the kpss-gcc registers. As the reg is shared also add the required syscon compatible.

Rework kpss-gcc driver Documentation to yaml Documentation.

It's not 'driver Documentation'. It's a DT binding for h/w.

Lot's of things are YAML. I prefer 'DT schema'

The subjects are bit long and get cut off as well. For the subject, something like:

dt-bindings: arm: msm: Convert kpss-gcc to DT schema

And similar for the other patch.
