This isn't the right place for this abstraction. Most of the setup code

Known issue:
If gpios are in use(export to userspace through sysfs interface, etc),
then call pl2303_release(unplug usb-serial convertor, modprobe -r,
etc),
will cause trouble, so we need to make sure there is no gpio user
before
call pl2303_release.
This is a real problem that

this patch add

PL2303 USB Serial devices always has GPIOs, this patch add
generic gpio support interfaces for pl2303 USB Serial devices
in pl2303_type_data and pl2303_serial_private, then use them
to add GPIOs support for one type of them, PL2303HXA.
