ENGR00175841 input: egalax_ts: fix touch can't work after suspend and reset.

if reset board during suspend, the controller can't success read
firmware version, it due to the chip needs some time to wake up, so
add 10 ms delay after wakeup chip in probe function.

don't need add delay in other code path, since the time was too short
to noticed in normal suspend/resume sequency.
