extcon: Modify the device name as extcon[X] for sysfs

Browse Source 
This patch modify the device name as extcon[X] for sysfs by using the 'extcon'
prefix word instead of separate device name. On user-space aspect, user would
find the some extcon drvier with extcon[X] pattern. So, this patch modify the
device name as following:
- /sys/class/extcon/[device name] -> /sys/class/extcon/extcon[X]
