dt-bindings: iio: Add cros ec proximity yaml doc 



Some cros ECs support a front proximity MKBP event via
'EC_MKBP_FRONT_PROXIMITY'. Add a DT binding to document this feature via
a node that is a child of the main cros_ec device node. Devices that
have this ability will describe this in firmware.

  Google's ChromeOS EC sometimes has the ability to detect user proximity.

  This is implemented on the EC as near/far logic and exposed to the OS

  via an MKBP switch bit.
