tpm: add TPM CRB device support

The CRB device was introduced with TPM 2.0 to be physical-bus agnostic
and defined in TCG PC Client Platform TPM Profile (PTP) Specification
Family “2.0” Level 00 Revision 01.03 v22

It seems to be required with Windows 10. It is also a simpler device
than FIFO/TIS.

This patch only support locality 0 since also the CRB device in QEMU
only supports this locality.
