Remove workaround code that it makes usb work in Artik

Excon does not work perfectly in Artik.
So I added the workaround code, which causes some strange USB initialization.

This problem disappears when the extcon value is always fixed at 1.
So I asked the kernel team to fix the extcon value to 1 and removed the workaround code.
If extcon is always 1, deviecd will not recognize when usb is disconnected, but it will work normally.

Conclusion: For targets where extcon does not work perfectly, deviced do not support usb connect/disconnect.
