The TPM class has some common shutdown code that must be executed for
all drivers. This adds some needed functionality for that.

-----
v2: Add Signed-off-by.
v3: Remove logically separate change.
v4: Add "acked-by" and "cc".

Yes, I think the else should be there. >From what I could tell, the intent is that the most generic will then call the least generic in the proper order, eg tpm class shutdown full should then call bus and driver shutdown, if they are defined. This allows each step to inject some action both before and after calling the lower level steps, and follows the same pattern used elsewhere.
