This adds support for driving the TPM on Socionext SynQuacer platform
using the driver for a memory mapped TIS frame.

v4:
- add ACPI support
- modify function and structure name

v3:
- prepare new module to handle TPM MMIO access on SynQuacer platform

v2:
- don't use read/write_bytes() to implement read/write16/32 since that uses
  the wrong address
