usb: typec: Add support for retimers
Introduce a retimer device class and associated functions that register
and use retimer "switch" devices. These operate in a manner similar to
the "mode-switch" and help configure retimers that exist between the
Type-C connector and host controller(s).
Type C ports can be linked to retimers using firmware node device
references (again, in a manner similar to "mode-switch").
There are no new sysfs files being created; there is the new retimer
class directory, but there are no class-specific files being created
there.
