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.
