[PATCH] dt-bindings: iio: dac: mcp47feb02: Fix binding issues

[Ariana Lazar <ariana.lazar@microchip.com>]

Change maxItems value from 8 to 1 for the channel number reg property.
Change example reg value from 0 to 0x60.
Fix a few typos in property descriptions.
Sort the part numbers in the enum list lexicographically.
