clk: mediatek: mt7622: Move infracfg to clk-mt7622-infracfg.c
The infracfg driver cannot be converted to clk_mtk_simple_probe() as
it registers cpumuxes, which is not supported on the common probing
mechanism: for this reason, move it to its own file.
While at it, also convert it to be a platform driver instead; to do
so, also add a .remove() callback for this driver.
During the conversion, error handling was added to the infracfg
probe function.
