clk: mediatek: Convert all remaining drivers to platform_driver's .remove_new()
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert all mediatek clk drivers from always returning zero in
the remove callback to the void returning variant.
