This patch change the name of various jig cables as 'JIG' because the name of
various jig cables are strange and ambiguous on user-space aspect. They include
the different information of either USB and UART state. It is never important
for user-space process. This patch unifies the name of jig cables as following:
- JIG-USB-ON -->|--> JIG
- JIG-USB-OFF -->|
- JIG-UART-ON -->|
- JIG-UART-OFF -->|

The logic for this default case is changed and it is not related to the
patch (unification of JIG). Could you split it into separate patch?
Rest looks fine.
