counter: 104-quad-8: Support Differential Encoder Cable Status
The ACCES 104-QUAD-8 series provides status information about the connection state of the differential encoder cable inputs. This patch implements support to expose such information from these devices.

+Description:
+ Read-only attribute that indicates whether a differential
+ encoder cable fault (not connected or loose wires) is detected
+ for the respective channel of Signal Y. Valid attribute values
+ are boolean. Detection must first be enabled via the
+ corresponding cable_fault_enable attribute.
