dt-bindings: usb: rts5411: Rename property 'companion-hub' to 'peer-hub'

In the context of USB the term 'companion-hub' is misleading, change the
name of the property to 'peer-hub'.

There are no upstream users of the 'companion-hub' property, neither in
the device tree, nor on the driver side, so renaming it shouldn't cause
any compatibility issues with existing device trees.

Changes in v24:
- patch added to the series
