[PATCH] Input: i8042 - move Dritek quirk so it also gets applied on resume

[Bruno Prémont]

This patch moves the quirk from from i8042_probe() to i8042_enable_kbd_port()
which is also called during resume.

I think it is safe to ignore failure to enable dritek. I would also prefer not 
to fail complete keyboard initialisation if the extension fails.

---
The Dritek quirk is also required on resume from S2RAM, doing it only at probe
time is not sufficient.
