drivers/thermal/ti-soc-thermal: Add hwmon support

Browse Source 
Expose ti-soc-thermal thermal sensors as HWMON devices.

  # sensors
  cpu_thermal-virtual-0
  Adapter: Virtual device
  temp1:        +54.2 C  (crit = +105.0 C)

  dspeve_thermal-virtual-0
  Adapter: Virtual device
  temp1:        +51.4 C  (crit = +105.0 C)

  gpu_thermal-virtual-0
  Adapter: Virtual device
  temp1:        +54.2 C  (crit = +105.0 C)

  iva_thermal-virtual-0
  Adapter: Virtual device
  temp1:        +54.6 C  (crit = +105.0 C)

  core_thermal-virtual-0
  Adapter: Virtual device
  temp1:        +52.6 C  (crit = +105.0 C)

Similar to imx_sc_thermal d2bc4dd91d.

No need to take care of thermal_remove_hwmon_sysfs() since
devm_thermal_add_hwmon_sysfs() (a wrapper around devres) is
used. See c7fc403e40.
