[PATCH 3/4] toshiba_acpi: Change HCI/SCI functions return code type

[Azael Avalos <coproscefalo@gmail.com>]

Currently the HCI/SCI read/write functions are returning
the status of the ACPI call and also assigning the
returned value of the HCI/SCI function.

This patch changes such functions, returning the value
of the HCI/SCI function instead of the ACPI call status.

The next patch will change all the HCI/SCI functions
to reflect the change made in this patch.
