Revert "i2c: designware: defer probe if child GpioInt controllers are not bound"

This reverts commit 0a4bb2abc3e56d7be6e69b050c88ba52c87e22bf.

This was reported to break the touchpad on at least some Thinkpads, and
while the revert has hit the i2c tree, it hasn't hit mine.  So I'm
reverting it directly just to have this resolved for the imminent 7.2
release.
