clk / soc: mediatek: Move mt8173 MMSYS to platform driver
There is no strong reason for this to use CLK_OF_DECLARE instead of being a platform driver. Plus, MMSYS provides clocks but also a shared register space for the mediatek-drm and the mediatek-mdp driver. So move the MMSYS clocks to a new platform driver and also create a new MMSYS platform driver in drivers/soc/mediatek that instantiates the clock driver.
