serial: core: Fix serial core port id, including multiport devices
We want to fix the serial core port DEVNAME to use a port id of the
hardware specific controller port instance instead of the port->line.
For example, the 8250 driver sets up a number of serial8250 ports
initially that can be inherited by the hardware specific driver. At that
the port->line no longer decribes the port's relation to the serial core
controller instance.
Let's fix the issue by assigning port->port_id for each serial core
controller port instance.
Fixes: 7d695d83767c ("serial: core: Fix serial_base_match() after fixing controller port name")
