clk: mediatek: mt8135-apmixedsys: Convert to platform_driver and module

Browse source 
Convert apmixedsys clocks to be a platform driver; while at it, also
add necessary error handling to the probe function, add a remove
callback and provide a MODULE_DESCRIPTION().

This driver is now compatible with an eventual module build.
