docs: dt: remove stale property-units.txt, link to current schema 



property-units.txt is not maintained anymore. New suffixes are now
supported that have not been added here.

To avoid people incorrectly think a given suffix is not in the list remove
the file entirely and point to the authoritative place where the
recommended suffixes are maintained.

Standard Unit Suffixes for Property names



Properties which have a unit of measure are recommended to have a unit

suffix appended to the property name. The list below contains the

recommended suffixes. Other variations exist in bindings, but should not

be used in new bindings or added here. The inconsistency in the unit

prefixes is due to selecting the most commonly used variants.



It is also recommended to use the units listed here and not add additional

unit prefixes.

- DO use common property unit suffixes for properties with scientific units.

  See property-units.txt.

  Recommended suffixes are listed at

  https://github.com/devicetree-org/dt-schema/blob/master/schemas/property-units.yaml



- DO define properties in terms of constraints. How many entries? What are

  possible values? What is the order?
