TPM: ACPI/PNP dependency removal
This patch pushes the ACPI dependency into the device driver code itself. Now, even without ACPI/PNP enabled, the device can be registered using the TIS specified memory space. This will however result in the lack of access to the bios event log, being the only implication of such ACPI removal.
