iio: accel: kxcjk-1013: Set label based on accel-location on 2-accel yoga-style 2-in-1s
Some 2-in-1 laptops / convertibles with 360° (yoga-style) hinges, use 2 KXCJ91008 accelerometers: 1 in their display using an ACPI HID of "KIOX010A"; and 1 in their base using an ACPI HID of "KIOX020A" Since in this case we know the location of each accelerometer, set the label for the accelerometers to the standardized "accel-display" resp. "accel-base" labels. This way userspace can use the labels to get the location. This was tested on a Medion Akoya E2228T MD60250.
