[PATCH v3 3/4] thermal: add sandbox driver

[Robert Marko]

Provide a simple sandbox driver for the thermal uclass.
It simply registers and returns 100 degrees C if requested.

Signed-off-by: Robert Marko <robert.marko at sartura.hr>

Changes in v3:
* Enable thermal class and temperature command in Sandbox SPL, flattree
and noinstall defconfigs as well to fix make check failing
