staging: omap-thermal: common code to expose driver to thermal framework This patch has the common thermal framework support for OMAP bandgap driver. It includes the zone registration and unregistration, the cpu cooling and the trip definitions. The trips definition is essentially one trip for passive cooling using the generic cpu cooling device and another one for thermal shutdown. The cpu cooling device is built based on the existing cpu freq table. The build should be agnostic to omap version, but relies that cpufreq is up and running by the time the driver registers the cpu cooling, as it relies on the table walk api from cpufreq.
