tpm: Split off tpm_crb_reset function

Split off the tpm_crb_reset function part from tpm_crb_realize
that we need to run every time the machine resets.

Also register our reset function with the sys

tpm: Split off tpm_crb_reset function

that we need to run every time the machine resets.

Also register our reset function with the system since TYPE_DEVICE
seems to not get a reset otherwise.

tpm: add CRB device

tpm_crb is a device for TPM 2.0 Command Response Buffer (CRB)
Interface as defined in TCG PC Client Platform TPM Profile (PTP)
Specification Family “2.0” Level 00 Revision 01.03

tpm: add CRB device

tpm_crb is a device for TPM 2.0 Command Response Buffer (CRB)
Interface as defined in TCG PC Client Platform TPM Profile (PTP)
Specification Family “2.0” Level 00 Revision 01.03 v22.

The PTP allows device implementation to switch between TIS and CRB
model at run time, but given that CRB is a simpler device to
implement, I chose to implement it as a different device.

The device doesn't implement other locality than 0 for now (my laptop
TPM doesn't either, so I assume this isn't so bad)

Tested with some success with Linux upstream and Windows 10, seabios &
modified ovmf. The device is recognized and correctly transmit
command/response with passthrough & emu. However, we are missing PPI
ACPI part atm.
