SecurityPkg: Add TPM PTP support in TPM2 device lib.
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.
