drivers/pc80/tpm: Disable device if TPM not present

If the TPM is not detected in the system it may	mean it	is inactive
due to enabled ME with active PTT. In such case, the chipset will route
the TPM	traffic to PTT CRB TPM on Intel systems.

If TPM is not probed, disable the PC80 TPM device driver, so that
coreboot will not generate improper SSDT ACPI table.
