drm/radeon/kms: add support for internal thermal sensors (v3)
rv6xx/rv7xx/evergreen families supported; older asics did
not have an internal thermal sensor.
Note, not all oems use the internal thermal sensor, so it's
only exposed in cases where it is used.
Note also, that most laptops use an oem specific ACPI solution for
GPU thermal information rather than using the internal thermal
sensor directly.
v2: export millidegrees celsius, use hwmon device properly.
v3: fix Kconfig
