4b67a0e467 ACPICA: FADT: set acpi_gbl_use_default_register_widths to TRUE by default
This returns the FADT support to the original behavior, which is
to use default register widths. However, now check each register
definition and report a warning if it differs from the default.
This is a first step to moving away from the default widths,
rather than outright believing the widths in all FADTs for all
machines, considered rather dangerous until more data is obtained.

06f5541960 ACPICA: FADT parsing changes and fixes
1) Update the register lengths for the PM1 event blocks. The
length must be divided by two in order to use these to access
the status registers.
2) Add run-time option to use default register lengths to override a
faulty FADT.
3) Add warning message if any of the X64 address structures contain a length
that does not match the legacy length earlier in the FADT.
4) Move all FADT warning messages into the ValidateFadt function.

50df4d8b0f ACPICA: Restructure includes into public/private
acpi.h now includes only the "public" acpica headers. All other
acpica headers are "private" and should not be included by acpica
users. One new file, accommon.h is used to include the commonly
used private headers for acpica code generation. Future plans
are to move all private headers to a new subdirectory.

Changed the acpi_hw_low_level_read and acpi_hw_low_level_write functions to
the public acpi_read and acpi_write to allow direct access to
ACPI registers.  Removed the "width" parameter since the width
can be obtained from the input GAS structure. Updated the FADT
initialization to setup the GAS structures with the proper
widths. Some widths are still hardcoded because many FADTs have
incorrect register lengths.
