This series clean up the sc8280xp CRD and X13s HID nodes somewhat and
marks the keyboard and touchpad as wakeup sources.
Included is also support for the alternate (second-source) touchpad
found on some X13s laptops. Note that the node is disabled for now as
ideally the boot firmware should be determining which touchpad is
actually populated.
With some additional fixes it is possible to have both nodes enabled and
letting Linux do the probing, but let's wait for a conclusion to the
discussion about whether that is desirable before enabling them both:

Interesting, what bootloader is used on these? Are you chainloading
something on top of Qualcomm's XBL UEFI?

We're using GRUB currently. Not sure how we'd go about implementing
this, and perhaps we'll just end up enabling both in DT instead
eventually.
