thermal: amlogic: Add hwmon support
Many monitoring tools read the CPU temperature using the hwmon
interface. Expose the thermal sensors on Amlogic boards as hwmon
devices.
Without this lm_sensors' "sensors" tool does not find any temperature
sensors. Now it prints:
cpu_thermal-virtual-0
Adapter: Virtual device
temp1: +44.7 C (crit = +110.0 C)
ddr_thermal-virtual-0
Adapter: Virtual device
temp1: +45.9 C (crit = +110.0 C)
