Those patches bring MMIO TPM TIS ACPI support in machvirt.

On ARM, the TPM2 table is added when the TPM TIS sysbus
device is dynamically instantiated in machvirt.

Also the TPM2 device object is described in the DSDT.

Many thanks to Ard for his support.

Tested with LUKS partition automatic decryption. Also
tested with new bios-tables-test dedicated tests,
sent separately.

Best Regards

Eric

History:

v6 -> v7:
- Collected Stefan and Igor's R-bs
- Eventually removed Acpi20TPM2 struct
- Updated the reference to the spec v1.2 rev8

v5 -> v6:
- added reference to the spec
- add some comments about LAML and LASA fields which are
  strangely undocumented in the spec for TPM2.0. So I kept
  the decision to keep the Acpi20TPM2 struct for documentation
  purpose.

v4 -> v5:
- Move of build_tpm2() in the generic acpi code was upstreamed
  but this does not correspond to latest proposed version.
- Rebase on top of edfcb1f21a

v3 -> v4:
- some rework in build_tpm2() as suggested by Igor
- Restored tpm presence check in acpi_dsdt_add_tpm()
- add the doc related patch

v2 -> v3:
- Rebase on top of Stefan's
  "acpi: tpm: Do not build TCPA table for TPM 2"
- brings conversion to build_append

v1 -> v2:
- move build_tpm2() in the generic code (Michael)
- collect Stefan's R-b on 3/3
