sysbus-fdt: falsely claim TPM CRB device is TPM TIS

Browse Source 
OVMF firmware is hard coded to recognize a TPM TIS device. If we lie,
the code will properly detect that it is a CRB device. In Linux, this
will cause the device to be not recognized properly but the separate
ACPI device will cause it to work regardless.
