TPM2 hardware may support PTP FIFO/TIS interface or PTP CRB interface. The original lib only handles PTP FIFO/TIS interface. This patch adds PTP CRB interface support. The current logic is that lib will runtime detect TPM device interface (CRB or FIFO/TIS) and call proper function to access hardware. It is compatible for old TPM2 FIFO/TIS device and new TPM2 CRB device.
