input: touchpanel: Fix abnormal crash caused by Synaptics TP



There was a abnormal kernel crash when TP resumes. The root
cause is that the call of reset_device in TP reusme function
may fail sometimes and watchdog's timeout occurred to make
kernel crash. After removing this useless reset-device by
undefine FB_READY_RESET, TP can work normally.
