Input: zinitix - don't fail if linux,keycodes prop is absent

When initially adding the touchkey support, a mistake was made in the
property parsing code. The possible negative errno from
device_property_count_u32() was never checked, which was an oversight
left from converting to it from the of_property as part of the review
fixes.

Re-add the correct handling of the absent property, in which case zero
touchkeys should be assumed, which would disable the feature.
