serial: max310x: use separate regmap name for each port
Use a separate regmap name for each port so they can each have their own
debugfs entry, allowing to access each port registers independently.
For example, a four channels/ports device like the MAX14830 will have four
entries in its regmap debugfs:
$ find /sys/kernel/debug/regmap -type d | grep spi0.0
/sys/kernel/debug/regmap/spi0.0-port0
/sys/kernel/debug/regmap/spi0.0-port1
/sys/kernel/debug/regmap/spi0.0-port2
/sys/kernel/debug/regmap/spi0.0-port3
