Subject: [PATCH v3 0/3] Add eusb2 repeater squelch detect parameter override

Add support for eusb2 repeater squelch detect parameter override via DT.

Squelch detect parameter adjusts the voltage level for the threshold used
to detect valid high-speed data.

Changes in v3:
- Moved status property to end of repeater node.
- Updated commit text as per comments received in bindings patch.
- Retained Krzysztof and Abel RB tags (since its upating commit text adding
  information in bindings code and moving status property in dt code)

- Added multipleOf property in bindings to reflect values can be multiple
