Add support for a ChromeOS EC proximity driver that exposes a "front"
proximity sensor via the IIO subsystem. The EC decides when front
proximity is near and sets an MKBP switch 'EC_MKBP_FRONT_PROXIMITY' to
notify the kernel of proximity. Similarly, when proximity detects
something far away it sets the switch bit to 0. For now this driver
exposes a single sensor, but it could be expanded in the future via more
MKBP bits if desired.

I'm fine with this, but want to leave a little time for others to take
one last look.  We've missed the coming merge window now anyway.

If I seem to have forgotten this in a couple of weeks, feel free to
give me a bump.

Ok no problem. Gwendal had some comments on v5 that may be applicable
here too but I think they mostly mean that the resume handler may not be
needed if cros ec is fixed. Having the resume handler shouldn't hurt
though unless I missed something. Gwendal?
