Subject: [PATCH v1 0/1] gpio: virtio: Fix config space reading.

The Virtio GPIO Linux driver reads the configuration space in a way not
conformant with the virtio specification. The hypervisor we are using is
strict in what it accepts so the current behavior causes a problem.

Builds on top of gpio/for-next, tested on Linux v6.5.7.
