Fix typos in Documentation/devicetree/bindings. The changes are in
descriptions or comments where they shouldn't affect functionality.

Few coefficients use default values multiple of 100, not 1000 (in the
example DTS and in the Linux driver):
moortec,mr75203.example.dtb: pvt@e0680000: moortec,ts-coeff-g:0:0: 61400 is not a multiple of 1000

The Devicetree bindings document does not have to say in the title that
it is a "binding", but instead just describe the hardware.
Drop trailing "bindings" in various forms (also with trailing full
stop):
find Documentation/devicetree/bindings/ -type f -name '*.yaml' \
-not -name 'trivial-devices.yaml' \
-exec sed -i -e 's/^title: \(.*\) [bB]indings\?\.\?$/title: \1/' {} \;

Add optional temperature coefficient properties:
*) moortec,ts-coeff-g
*) moortec,ts-coeff-h
*) moortec,ts-coeff-cal5
*) moortec,ts-coeff-j
If defined they shall be used instead of defaults.
The coefficients were added to device tree on top of the series property
(which can be used to select between series 5 and series 6), because
coefficients can vary between product and product, and code defaults might
not be accurate enough.

Add optional "moortec,ts-series" property to define the temperature
equation and coefficients that shall be used to convert the digital
output to value in milli-Celsius.
Supported series: 5 (default) and 6.
Series 5:
T = G + H * (n / cal5 - 0.5) + J * F
Where: G = 60, H = 200, cal5 = 4094, J = -0.1, F = frequency clock in MHz
Series 6:
T = G + H * (n / cal5 - 0.5)
Where: G = 57.4, H = 249.4, cal5 = 4096

Add support for mr76006 pre-scaler which provides divide-by-2 scaling of
the input voltage, so that it can be presented to the VM for measurement
within its range (the VM input range is limited to -0.1V to 1V).
The new "moortec,vm-pre-scaler-x2" property lists the channels that use
the mr76006 pre-scaler.
The driver will use this list to multiply the voltage result by 2, to
present to the user with the actual voltage input source.

Change "intel,vm-map" property to be optional instead of required.
The driver implementation indicates it is not mandatory to have
"intel,vm-map" in the device tree:
- probe doesn't fail in case it is absent.
- explicit comment in code - "Incase intel,vm-map property is not
defined, we assume incremental channel numbers".

The correct syntax for JSON pointers begins with a '/' after the '#'.
Without a '/', the string should be interpreted as a subschema
identifier. The jsonschema module currently doesn't handle subschema
identifiers and incorrectly allows JSON pointers to begin without a '/'.
Let's fix this before it becomes a problem when jsonschema module is
fixed.
