Vadim Bendebury 5a6bb19a88 tpm: reset communications channels when resetting TPM
TPM resets happen asynchronously, conceivably there is some interface
(i2cs or sps) activity under way when TPM is reset.

Sps driver provides a means of disconnecting the client of the driver,
while the i2cs driver does not. Come to think of it, there is no real
need to provide a special function to disconnect a client, this makes
API simpler and allows to add driver initialization to the client
registration function.

To make tpm_registers.c more flexible - allow to register a callback
for interface initialization, this way when TPM is reset, the
interface can be also re-initialized and is guaranteed to start from
scratch after reset.

TEST=both firmware_TPMExtend and firmware_TPMKernelVersion autotests
