acpi: pvpanic-isa: use AcpiDevAmlIfClass:build_dev_aml to provide device's AML
.. and clean up not longer needed conditionals in DSTD build code
pvpanic-isa 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.
