There were previous attempts to "merge" the toshiba SMM module to the
toshiba_acpi one, they were trying to imitate what the old toshiba
module does, however, some models (TOS1900 devices) come with a
"crippled" implementation and do not provide all the "features" a
"genuine" Toshiba BIOS does.

This patch adds a new device called toshiba_acpi, which aim is to
enable userspace to access the SMM on Toshiba laptops via ACPI calls.

Creating a new convenience _IOWR command to access the SCI functions
by opening/closing the SCI internally to avoid buggy BIOS, while at
the same time providing backwards compatibility.

Older programs who wish to access the SMM on newer models can do it
without much code change, as the toshiba.h header was modified to
reflect these changes as well as adds all the toshiba_acpi paths
and commands.

This and the other 2 are queued to for-review. They will remain there for a few
days to give others a chance to review. After that, I will provide a thorough
review and move them into for-next for 4.3

They do pass all my preliminary tests, checkpatch, build, and ninja-check.

As this is the first series that I've received since enabling a lot of new
automation, I wanted to say thanks for clean series that is ready review. Nice.
