Input: iqs7222 - report malformed properties

Nonzero return values of several calls to fwnode_property_read_u32()
are silently ignored, leaving no way to know the properties were not
applied in the event of an error.

Solve this problem by evaluating fwnode_property_read_u32()'s return
value, and reporting an error for any nonzero return value not equal
to -EINVAL which indicates the property was absent altogether.
