Subject: next: x86_64: ahci 0000:00:1f.2: probe with driver ahci failed with
 error -12

The qemu-x86_64 boot failed with today's Linux next-20240814 tag due to
following crash.

The catch here is the crash seen on both x86_64 device and qemu-x86_64
but x86_64 device is able to boot successfully.

Reported-by: Linux Kernel Functional Testing <lkft@...aro.org>
