Input: edt-ft5x06 - add delay after waking up

The touch controller needs some time to wake-up after setting the wake-up
gpio. Without having a delay after wake-up probing regularly fails in
edt_ft5x06_ts_identify() with an error (i.e. EREMOTEIO) that was caused
by a failed i2c transfer.

The datasheet sets the wake-up time to 5 ms, although it is not entirely
clear.
