SoC driver patches. Highlight in this pull request is, that we got the mmsys mess cleaned up. In MediaTek "mmsys" is IP block which holds multi-media devices and their corresponding clocks muxes. In the past the clocks and multi-media system used the same compatible (ouch) which broke graphics quite some time ago. After several different approaches how to fix the mess, we now got a mmsys SoC driver which is responsible for probing the clock and multi-media parts of the IP block. This now allows us to have graphics support on the MT8173 based Chromebooks, which is nice and will allow others developers who don't have a servo board to debug the device and (hopefully) help to get the missing bits upstream. The effort is not yet finished, but I hope for v5.9 we will see also graphics support on the Bananapi-R2.
