This adds the initial DT for the Lenovo Miix 630 laptop.  Supported
functionality includes USB (host), microSD-card, keyboard, and trackpad.

What is cls?

How much of this will be reusable with the other laptops?

Clamshell.  I left a comment in the file that is intended to clarify
this.  If one does some digging, they should find a fair number of
"cls" references within the firmware and windows.

The intent is that all the common stuff, which I expect is >90%, is in
the cls.dtsi so that we don't have multiple copies of it.  Variances,
such as the SD detect GPIO stuff we've discovered would be in the
individual dtb.  Or at-least, that is the idea.  I'm open to
suggestions.

I'm unable to post dts files based on the HP/Asus at this time, but
hopefully that changes soon.  Otherwise, Its my goal that this
provides a good framework for adding those devices.

I was under the impression that the Miix 630 came with Windows, and the
firmware therefore provided (as least a simulacrum of) ACPI. Why do we
need a DT?

I think it would be better to consistently use "clamshell" (e.g. rename
this to msm8998-clamshell.dtsi), and mention the "cls" terminology in
the comment if that's necessary.

Please give this a real compatible string rather than forcing the ACPI
HID in.

Thanks,
Mark.
