ACPI: make remove callback of ACPI driver void
For bus-based driver, device removal is implemented as:
1 device_remove()->
2 bus->remove()->
3 driver->remove()
Driver core needs no inform from callee(bus driver) about the
result of remove callback. In that case, commit fc7a6209d571
("bus: Make remove callback return void") forces bus_type::remove
be void-returned.
Now we have the situation that both 1 & 2 of calling chain are
void-returned, so it does not make much sense for 3(driver->remove)
to return non-void to its caller.
So the basic idea behind this change is making remove() callback of
any bus-based driver to be void-returned.
This change, for itself, is for device drivers based on acpi-bus.
