clk: mediatek: mt8516: Move apmixedsys clock driver to its own file
In preparation for migrating mt8516 clocks to the common simple
probe mechanism, convert the apmixedsys to be a separated
platform driver and move it to clk-mt8516-apmixedsys.c.
While at it, also fix some indentation issues.
During the conversion, error handling was added to the apmixedsys
probe function.
