a65615df5b 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.

65c9ad77cb clk: mediatek: Add MODULE_DEVICE_TABLE() where appropriate
Add a MODULE_DEVICE_TABLE() on all clocks that can be built as modules
to allow auto-load at boot.

c50e2ea650 clk: mediatek: mt7622-apmixedsys: Add .remove() callback for module build
Add a .remove() callback to the apmixedsys driver to allow full module
build; while at it, also change the usage of builtin_platform_driver()
to module_platform_driver() to actually make use of the new callback.

9aed98adf6 clk: mediatek: mt7622: Move apmixedsys clock driver to its own file
In preparation for migrating mt7622 clocks to the common simple
probe mechanism, move apmixedsys clocks to a different file.
While at it, use the builtin_platform_driver() macro for it.

During the conversion, error handling was added to the apmixedsys
probe function.
