dt-bindings: use capital "OR" for multiple licenses in SPDX

Documentation/process/license-rules.rst and checkpatch expect the SPDX
identifier syntax for multiple licenses to use capital "OR". Correct it
to keep consistent format and avoid copy-paste issues.

Correct also the format // -> .* in few Allwinner binding headers as
pointed out by checkpatch:

WARNING: Improper SPDX comment style for 'include/dt-bindings/reset/sun50i-h6-ccu.h', please use '/*' instead

dt-bindings: hwmon: correct indentation and style in examples

Fix mixed indentation to 4-spaces, remove unnecessary suffix from
i2c node name and use lower-case hex. No functional impact.

dt-bindings: hwmon: Allow specifying channels for lm90

Add binding description for temperature channels. Currently, support for
label and temperature-offset-millicelsius is implemented.

dt-bindings: hwmon: Add compatible string for ADT7481 in lm90

This will allow binding the driver with the device from the device tree.

This device can work in extended temperature measurement mode, so add it
also to the list of devices that support 'ti,extended-range-enable'.

dt-bindings: hwmon: lm90: add ti,extended-range-enable property

Some devices can operate in an extended temperature mode.
Therefore add a boolean ti,extended-range-enable to be able to
select this feature in the device tree node. Also make sure that this
feature can only be enabled for the devices supporting this feature.

dt-bindings: hwmon: lm90: Drop Tegra specifics from example

There's no need to complicate examples with a platform specific macro.
It also complicates example parsing to figure out the number of
interrupt cells in examples (based on bracketing).

dt-bindings: hwmon: lm90: do not require VCC supply

The LM90-like sensors usually need VCC supply, however this can be
hard-wired to the board main supply (like in SiFive HiFive Unmatched
RISC-V board). Original bindings made VCC supply as required but in
practice several other boards skipped it. Make it optional.
