dt-bindings: arm: msm: Convert and split kpss-acc driver Documentation to yaml

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, split the Documentation
to 2 different schema, v1 as clock-controller and v2 for
power-manager as per msm-3.10 specification, the exposed regs handle
power manager.
