cr50: introduce tpm task skeleton
TPM command processing should not be happening on the interrupt
context.
This patch adds a skeleton of the task which handles TPM functions. It
initializes the TPM and then enters endless loop waiting for an event
trigger from interrupt, which happens when a valid FIFO message is
received.
