Fixed a problem with Index Fields where the index was not incremented
for fields that require multiple writes to the index/data registers
(Fields that are wider than the data register.)

Fixed a problem with all Field objects where a write could go beyond the
end-of-field if the field was larger than the access granularity and
therefore required multiple writes to complete the request.  An extra
write beyond the end of the field could happen inadvertently.

Fixed a problem with Index Fields where a BUFFER_OVERFLOW error would
incorrectly be returned if the width of the Data Register was larger
than the specified field access width.

Completed fixes for LoadTable() and Unload() and verified their
operation.  Implemented full support for the "DdbHandle" object
throughout the ACPI CA subsystem.

Implemented full support for the MADT and ECDT tables in the ACPI CA
header files.  Even though these tables are not directly consumed by
ACPI CA, the header definitions are useful for ACPI device drivers.

Integrated resource descriptor fixes posted to the Linux ACPI list.
This included checks for minimum descriptor length, and support for
trailing NULL strings within descriptors that have optional string
elements.

Fixed a problem where the SMI_CMD register could be written even if it
was not supported on the platform (when FADT.SMI_CMD is zero)
