input: touchscreen: increase number of checks for touch controller status



Before doing any i2c read/write, driver needs to check the value
of QUERY buffer to know if the controller is in ready or busy state.
Sometime, it takes more number of checks to know the status.
So this change increases the number of checks to know the ITE tech
touch controller status.

This is a propagated patch from 3.18 kernel 'commit 60589278b8e7 ("input:
touchscreen: increase number of checks for touch controller status")
