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.

platform/x86: wireless-hotkey: remove hardcoded "hp" from the error message

This driver is no longer specific to HP laptops so "hp" in the error
message is no longer applicable.

platform/x86: Rename hp-wireless to wireless-hotkey

This driver was originally intended to support some HP laptops, but
later support was added for Xioami and AMD laptops.

Rename it to make it clear that it supports a larger variety of
systems.
