ACPI 6.0 support for fwts

[Colin Ian King]

The ACPI 6.0 specification [1] was recently released, so fwts should now start to support this.

For example, add support for XENV, STAO.. tables.
Add method checks for

    _BTH, _CR3, _LPI, _MTL, _PRR, _RDI, _RST, _TFP, _TSN.

etc.

This bug should be expanded to enumerate all the changes that need to be added to fwts

[Alex Hung (alexhung)]

Tests for listed control methods are implemented and waiting for review. Next steps will be the implementation for ACPI tables

ACPI Tables TODOs;

From Table 5-30
EINJ, MSCT, MPST, PMTT, NFIT, PCCT, RASF

From Table 5-31
DRTM, ETDT, IBFT, IVRS, WPBT

[Alex Hung (alexhung)]

Updates to #2:

1. ETDT is obsolete and superseded by "HPET"
2. RASF seems to be uninterested (an element with 12 bytes) and a template cannot be generated by "iasl -T RASF".

This leaves us ACPI Tables TODOs:

From Table 5-30
EINJ, MSCT, MPST, PMTT, NFIT, PCCT

From Table 5-31
DRTM, IBFT, IVRS, WPBT

[Colin Ian King (colin-king)]

Note: I've searched my data base of ACPI tables and cannot find any instances of RASF being used. So it is an obscure and infrequently used table.

[Colin Ian King (colin-king)]

I've scanned my database of ACPI tables, here are the number if instances I found of the remaining tables to implement:

EINJ 1.52%
MSCT 0.26%
IVRS 0.23%
MPST 0
PMTT 0
NFIT 0
PCCT 0
DRTM 0
IBFT 0
WPBT 0

So EINJ, MSCT and IVRS look like the most relevant ones to implement first

[Alex Hung (alexhung)]

EINJ and MSCT are sent for reviews at http://patchwork.ozlabs.org/patch/612131/ and http://patchwork.ozlabs.org/patch/612130/, respectively

[Alex Hung (alexhung)]

MPST, PMTT, NFIT and PCCT are also implemented

[Alex Hung (alexhung)]

Now only four (IVRS DRTM IBFT WPBT) tables from external specs, ex. in Table 5-31, are not implemented.

[Alex Hung (alexhung)]

DRTM and WPBT are implemented and will be available in next release.

[Alex Hung (alexhung)]

IBFT is old (2009) and it seems nobody is using it. Let's skip it.
