gpio: intel_gpio: Initialise or0 and or1
In intel_gpio_set_flags the two variables or0 and or1 may be used uninitialised. Correct this by setting initial values in the declaration. Also there is no need to use '|=' when the initial value is 0 and there is only one assignment performed to each variable so just use '=' instead. This issue was found by Smatch.
