Subject: [PATCH v16 1/3] usb: typec: tcpci: move tcpci.h to include/linux/usb/

USB PD controllers which consisting of a microcontroller (acting as the TCPM)
and a port controller (TCPC) - may require that the driver for the PD
controller accesses directly also the on-chip port controller in some cases.

Move tcpci.h to include/linux/usb/ is convenience access TCPC registers.
