extcon: usbc-tusb320: Add support for TUSB320L

[ Upstream commit ce0320bd3872038569be360870e2d5251b975692 ]

TUSB320L is a newer chip with additional features, and it has additional steps
in its mode changing sequence:
 - Disable CC state machine,
 - Write to mode register,
 - Wait for 5 ms,
 - Re-enable CC state machine.
It also has an additional register that a revision number can be read from.

Add support for the mode changing sequence, and read the revision number during
probe and print it as info.
