The NXP PTN36502 is used in the Fairphone 5 smartphone, add a driver for
it so we can soon enable DisplayPort over USB-C on this phone.

Changes in v2:
- Use FIELD_PREP+GENMASK for register values
- Move FIELD_GET for chip revision from macro to code (to align with
new register definition style)
- Fix bad code alignment at ptn36502_bridge_attach function
- Pick up tags
- Link to v1: https://lore.kernel.org/r/[email protected]

Document bindings for this Type-C USB 3.1 Gen 1 and DisplayPort v1.2
combo redriver.
The PTN36502 can also run in GPIO mode where it is configured
differently, without any I2C connection, but this is not supported yet.
