toshiba_acpi: make remove_device() and add_device() void 

remove_device() and add_device() are not related to ACPI APIs, it does not
make sense to return acpi_status for both functions.

Current implementation of add_device() always AE_OK, thus the return value
checking for add_device() always return false for ACPI_FAILURE(status).
This patch makes add_device() to be void and remove the unnecessary return
value checking.

remove_proc_entry() won't fail, thus change remove_device() to be void.
