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:
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

- 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
