It this option is selected, then the NxWM:CTouchscreen listener
thread will call a function arch_tcinitialize(NXWM_TOUCHSCREEN_DEVNO)
in order to instantiate the touchscreen driver at path
NXWM_TOUCHSCREEN_DEVPATH. If NXWM_TOUCHSCREEN_DEVINIT is not
selected, then the NxWM:CTouchscreen listener thread will assume
that the driver has already been initialized at
NXWM_TOUCHSCREEN_DEVPATH.
NOTE that in the kernel build, all touchscreen initialize must be
performed in kernel logic prior to the execution of NxWM.
