Due to no platforms use a multi-funtion pin to detect VBUS
status until now when support dual role mode, prefer not to
support it anymore;
Another reason is that the controller doesn't support idle status,
the dual role port works as device or as host, using an IDDIG pin
is good enough, this will help to save another multi-function pin;
And fix a typo of 'neede';
Last modify example using VBUS to turn on/off device, for device
only mode, the driver doesn't get extcon.

These two HW of wakeup don't follow MediaTek internal IPM rule,
and both use a specific way, like as early revision of mt8173.
Due to the index 2 already used by many DTS, it's better to keep
it unchanged for backward compatibility, treat specific ones without
following IPM rule as revision 1.x, meanwhile reserve 3~99 for
later revision that following the IPM rule.
