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

This reverts commit 0a4bb2abc3e56d7be6e69b050c88ba52c87e22bf.

The reverted commit causes a regression on ThinkPad T14s Gen 4 (AMD):
the touchpad's I2C controller fails with lost arbitration errors,
because it delays i2c-designware's probe by roughly 500ms, which
shifts the touchpad's first HID descriptor fetch into a window where
the platform's embedded controller is still acting as a secondary I2C
bus master. Debug tracing confirms the GpioInt dependency check itself
behaves correctly (it defers appropriately and confirms the GPIO
controller is bound); the arbitration failure happens roughly a
second after the check passes, when i2c_hid_acpi's own probe attempts
its first transaction.

The original fix is still needed for the Lenovo Yoga 7 14AGP11
touchscreen race the commit addressed, but a corrected version will
be resubmitted once the EC bus-mastering interaction is understood
and handled properly, rather than reintroducing a different
regression on more widely-used ThinkPad hardware in the meantime.
