Provide thermal zone to read thermal sensor
in the SoC. We can read all the thermal sensors
value in the SoC by the node /sys/class/thermal/
In mtk_thermal_bank_temperature, return -EAGAIN instead of -EACCESS
on the first read of sensor that often are bogus values.
This can avoid following warning on boot:
thermal thermal_zone6: failed to read out thermal zone (-13)
