Subject: [PATCH v6 25/54] 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.
