Replace the prose for properties dependent on specific "enable-method"
values with schemas defining the same requirements.
Both "qcom,acc" and "qcom,saw" properties appear to be required for any
of the Qualcomm enable-method values, so the schema is a bit simpler
than what the text said. The properties are also needed on some Qualcomm
platforms with other enable-method values. It's limited to Cortex A53
based platforms so use that to disable the properties. The references
to arm/msm/qcom,saw2.txt and arm/msm/qcom,kpss-acc.txt are out of date,
so just drop them.

The SAW2 device can optionally provide a voltage regulator supplying the
CPU core, cluster or L2 cache. Change the boolean 'regulator' property
into a proper regulator description. This breaks schema compatibility
for the sake of properly describing the regulator.

Define compatible strings for SAW2 units present on MSM8960, IPQ4019
and IPQ8064. There is no need to include SAW version into the compat
string, so just use the SoC and SAW2 kind.
Also add missing L2 SAW2 compatibles for MSM8974 and APQ8084, they
follow the existing CPU SAW2 strings.

The Qualcomm SPM / SAW2 device is described in two bindigns files:
arm/msm/qcom,saw2.txt and soc/qcom/qcom,spm.yaml. Merge the former into
the latter, adding detailed device node description. While we are at it,
also rename qcom,spm.yaml to qcom,saw2.yaml to follow the actual
compatible used for these devices.
The regulator property is retained as is. It will be changed in the
later patches.
