Ming Lei 1ded7ea47b USB: ch341 serial: fix port number changed after resume 
This patch fixes the following bug:
	.plug ch341 usb serial port into a hub port;
	.ch341 driver bound to the device and /dev/ttyUSB0 comes
	.open /dev/ttyUSB0 by minicom and we can use the serial successfully
	.suspend the ch341 usb serial device(such as: echo suspend > power/level)
	.resume the ch341 usb serial device (such as: echo on > power/level)
	.new port /dev/ttyUSB1 comes ,and the original /dev/ttyUSB0 still exists,
but is no longer usable by minicom

The patch adds suspend and resume callback to ch341 usb driver to prevent it
from unbinding during suspend. The /dev/ttyUSB0 is not released until being
closed, so /dev/ttyUSB1 comes after resume, and the original /dev/ttyUSB0 is
no longer usable by minicom. It is really a mess for a minicom user.

This patch also adds the reset_resume callback to make it usable after resuming
from STR or hibernation, for generally STR or hibernation will make the vbus
of root-hub lost.

Finally enable the driver's supports_autosuspend, for the device is in working
order with it.
