pinctrl: amd: Add PM debugging message for turning on/off wakes

Browse Source 
The GPIOs for devices not in _AEI/_EVT such as touchpad or touchscreen
won't have wakeup turned on until the suspend sequence starts.

Due to code in amd_gpio_suspend_hibernate_common() masking the interrupt
can make this difficult to follow what's going on.  Add an explicit
debugging message to tell when that was turned on/off.
