tpm/tpm_svsm: support TPM_CHIP_FLAG_SYNC
This driver does not support interrupts, and receiving the response is
synchronous with sending the command.
Enable synchronous send() with TPM_CHIP_FLAG_SYNC, which implies that
->send() already fills the provided buffer with a response, and ->recv()
is not implemented.
Keep using the same pre-allocated buffer to avoid having to allocate
it for each command. We need the buffer to have the header required by
the SVSM protocol and the command contiguous in memory.
