samsung ypr0: Include getty service in the patched firmware for usb serial shell access.
The getty service mointors /dev/ttyGS0 (also created by the patched firmware). When the g_serial.ko module is loaded this automatically enables shell access via usb. It exposes a cdc-acm device to the host which is compatible to linux (usb_serial.ko) and windows. The g_serial.ko is not included module can be build from the YP-R0 open source package provided by samsung. It can be loaded via rc.user on the internal memory.
