Would it make sense to split this patch into two parts? One general
"add i.MX6 SoloLite support" and then the "add mx6slevk board board
support"?

I haven't looked into the manual, but are these the clock registers?
If so, is it necessary to set them to 0xffffffff? Or are these
already the default reset values?
