dt-bindings: usb: smsc,usb3503: Correct indentation and style in DTS example

JIRA: https://issues.redhat.com/browse/RHEL-116016
Conflicts:
* Avoiding commit 2d09115 ("dt-bindings: white-space cleanups")
  that performed a treewide white space cleanup

commit 1b4dab8
Author: Krzysztof Kozlowski <[email protected]>
Date: Mon, 24 Mar 2025 13:51:42 +0100

  DTS example in the bindings should be indented with 2- or 4-spaces and
  aligned with opening '- |', so correct any differences like 3-spaces or
  mixtures 2- and 4-spaces in one binding.

  No functional changes here, but saves some comments during reviews of
  new patches built on existing code.
