Some Toshiba laptops do not come with the ECO led installed, however,
the driver is registering support for it when it should not.

This patch makes the toshiba_eco_mode_available function more robust
in detecting ECO led capabilities, not registering the led on laptops
that do not support it and registering the led when it really does.

The ECO led function now returns 0x8e00 (Not Installed) by querying
with in[3] = 0, whenever theres no physical LED installed, and
returning 0x8300 (Input Data Error) when it is, however, there are
some BIOSes that have stub function calls not returning anything and
and the LED device was being registered too, hence the change of the
default return value from 1 to 0.

This was "toshiba_acpi: Change sci_open function return value"

Some Toshiba laptops have "poorly implemented" SCI calls on their
BIOSes and are not checking for sci_{open, close} calls, therefore,
the sci_open function is failing and making some of the supported
features unavailable (kbd backlight, touchpad, illumination, etc.).

This patch checks whether we receive TOS_NOT_SUPPORTED and returns
1, making the supported features work on such laptops.

In the case that some laptops really do not support the SCI, all the
SCI dependent functions check for TOS_NOT_SUPPORTED, and thus, not
registering support for the queried feature.

The current code just returns -EINVAL because mode can't be equal to
both 1 and 2.

Also this function is messy so I have cleaned it up:
1) Remove initializers like "int time = -1".  Initializing variables to
   garbage values turns off GCC's uninitialized variable warnings so it
   can lead to bugs.
2) Use kstrtoint() instead of sscanf().
3) Use SCI_KBD_MODE_FNZ and SCI_KBD_MODE_AUTO instead of magic numbers 1
   and 2.
4) Don't check for "mode == -1" because that can't happen.
5) Preserve the error code from toshiba_kbd_illum_status_set().
