89b96e3244 dt-bindings: serial: add common properties schema for UART children
Properties should be defined in only one place, thus add new
serial-peripheral-props.yaml schema with definition of common properties
for UART-connected devices (children of UART controller): current-speed
and max-speed.  The schema can be referenced by individual devices using
these properties.

There exist some embedded controllers (like Microsoft SAM found on

22088bbb02 dt-bindings: serial: re-order entries to match coding convention
The DT schema coding convention expressed in
Documentation/devicetree/bindings/example-schema.yaml expects entries in
following order:
 - properties, patternProperties
 - required
 - if blocks, allOf with if-blocks
 - additionalProperties/unevaluatedProperties

Re-order few schemas to match the convention to avoid repeating review
comments for new patches using existing code as template.  No functional
changes.

0c559bc8ab dt-bindings: serial: restrict possible child node names
The re-usable serial.yaml schema matches every property with ".*"
pattern, thus any other schema referencing it will not report unknown
(unevaluated) properties.  This hides several wrong properties.  It is
a limitation of dtschema, thus provide a simple workaround: expect
children to be only of few names matching upstream usage (Bluetooth,
GNSS, GPS and MCU).
