extcon: sm5502: Change internal hardware switch according to cable type

This patch changes internal hardware DP_CON/DM_CON switch according to
cable type. The SM5502 MUIC device can set hardware switch as following:
- OPEN (not connected state) / USB / UART / AUDIO
Also, this patch set VBUSIN switch according to cable type.
