tpm-be: update optional function pointers
QEMU code doesn't generally have assert() for mandatory
callbacks/function pointers, probably because the crash is pretty
obvious. Document the methods instead of going into the code.
Make get_tpm_options() mandatory to implement (since all
backend implementation have it).
