SecurityPkg: Add TPM PTP detection in TPM12 device lib.
The TPM RequestUseTpm API can only set register to
use the hardware, but it can not be used to distinguish
TPM12 or TPM2 device.
TPM PTP defines same address with TIS, so we need
detect the TPM device is PTP or TIS in RequestUseTpm.
Also, Tcg2Config driver call RequestUseTpm to detect
TPM hardware device. So we have to add check here.
There is no need to support PTP CRB style SubmitCommand(),
because TPM2 device can not accept TPM12 style command.
This patch also uses TpmTis.h instead of duplicate
definition.
