Subject: [PATCH] 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.
