ACPICA: Removed all 16-bit support.

Support for 16-bit ACPICA has been completely removed since it is
no longer necessary and it clutters the code. All 16-bit macros,
types, and conditional compiles have been removed, cleaning up
and simplifying the code across the entire subsystem.
DOS support is no longer needed since the Linux firmware kit
is now available.
