Bug description:
Commit 5467801f1fcb ("gpio: Restrict usage of GPIO chip irq members
before initialization") attempted to fix a race condition that lead to
a NULL pointer, but in the process caused a regression for _AEI/_EVT
declared GPIOs.
This manifests in messages showing deferred probing while trying to
allocate IRQs like so:
amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x0000 to IRQ, err -517
amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x002C to IRQ, err -517
amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x003D to IRQ, err -517
[ .. more of the same .. ]
The code for walking _AEI doesn't handle deferred probing and so this
leads to non-functional GPIO interrupts.
