Distributions such as Fedora, Ubuntu and Gallium don't currently have a means to support Baytrail Chromebooks and other platforms with the same build [1][2] due to incompatible platform drivers.
Add MCLK management to reuse this machine driver for Baytrail platforms and solve this coexistence problem at last. UCM files are provided at [3] and will eventually be submitted to the new repo.
The legacy byt-max98090 machine driver is still maintained but can only be used when the other Atom/DPCM driver is not compiled in, or when users don't want to configure extra mixers required by the Atom/sst driver.
Tested on Lenovo 100s Baytrail Chromebook w/ Mr. Chromebox BOOT_STUB firmware and Acer R11 Cherrytrail Chromebook

Yes, if that's alright with you I'll clean this up in all Intel machine drivers in one patch since this is all copy-paste. I just need a clear indication on what the preferred means of string comparisons is...
