tpm: rng: Add driver model interface for TPM RNG device
The TPM device has a builtin random number generator(RNG)
functionality. Expose the RNG functions of the TPM device to the
driver model so that they can be used by the EFI_RNG_PROTOCOL if the
protocol is installed.
Also change the function arguments and return type of the random
number functions to comply with the driver model api.
