Fixes some problems introduced by late changes to the table as it
was added to the ACPI 5.0 specification.
Both the table compiler and the disassembler and the main header
support for the table.
Update the comments that explain why ACPICA cannot use bitfields.
/*
* Note: C bitfields are not used for this reason:
*
* "Bitfields are great and easy to read, but unfortunately the C language
* does not specify the layout of bitfields in memory, which means they are
* essentially useless for dealing with packed data in on-disk formats or
* binary wire protocols." (Or ACPI tables and buffers.) "If you ask me,
* this decision was a design error in C. Ritchie could have picked an order
* and stuck with it." Norman Ramsey.
