Remove the argument-less .align directive in sys/i386/bios/smapi_bios.S.
Specifying no argument is undocumented in the gas manual, and clang's
integrated assembler refuses to parse it. Also, removing it causes no
change at all in the resulting object file.

Fix build (including both asm.h and asmacros.h is evil).

Despite my best efforts the Linux way of doing this is the only
way that works correctly.

- Remove unused function.
- Move declaration of variables to .S file.

Use __FBSDID().

- Removed unecesary code.
- Correct smapi32_new() asm (still doesn't work.)
- Attach to mainboard not isa.

A driver for the System Management Application Program
Interface (SMAPI) BIOS, which is present on some IBM
Thinkpad models (560, 600, 770 to name a few.)

The SMAPI BIOS provides access to System Information,
System Configuration, and Power Management.
