thermal: of: improve of-thermal sensor registration API
Different drivers request API extensions in of-thermal. For this reason, additional callbacks are required to fit the new drivers needs. The current API implementation expects the registering sensor driver to provide a get_temp and get_trend callbacks as function parameters. As the amount of callbacks is growing, this patch changes the existing implementation to use a .ops field to hold all the of thermal callbacks to sensor drivers. This patch also changes the existing of-thermal users to fit the new API design. No functional change is introduced in this patch.
