toshiba_acpi: Change HCI/SCI functions return code type
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, however, only the HCI/SCI status is being checked. This patch changes such functions, returning the value of the HCI/SCI function instead of the ACPI call status, eliminating one parameter, and returning something useful that indeed is being checked.
