acpi: tpm-tis: use AcpiDevAmlIfClass:build_dev_aml to provide device's AML

.. and clean up not longer needed conditionals in DSTD build code
tpm-tis AML will be fetched and included when ISA bridge will
build its own AML code (including attached devices).

Expected AML change:
    the device under separate _SB.PCI0.ISA scope is moved directly
    under Device(ISA) node.
