usb: typec: intel_pmc_mux: Silence snprintf() output truncation warning 

In the function pmc_mux_port_debugfs_init() the buffer for
the name of the port is limited to six bytes. That makes the
compiler think that the output of "port%d" may be truncated.
That can't actually happen as the interface can support
maximum of eight ports. To make the compiler happy just
increase the buffer to where the warning goes away.
