thermal: armada: Give meaningful names to the thermal zones

After registration to the thermal core, sysfs will make one entry
per instance of the driver in /sys/class/thermal_zoneX and
/sys/class/hwmon/hwmonX, X being the index of the instance, all of them
having the type/name "armada_thermal".

Until now there was only one thermal zone per SoC but SoCs like Armada
A7K and Armada A8K have respectively two and three thermal zones (one
per AP and one per CP) and this number is subject to grow in the future.

Use dev_name() instead of the "armada_thermal" string to get a
meaningful name and be able to identify the thermal zones from
userspace.
