On AMD Zen acpi_dev_irq_override() by default prefers the DSDT IRQ 1

This causes the keyboard to malfunction on some laptop models
(see Links), all models from the Links have an INT_SRC_OVR MADT entry
for IRQ 1.

One of the laptops fixed by a9c4a912b7dc, PCSpecialist Elimina Pro 16 M
[1], seems to have no INT_SRC_OVR entry for IRQ 1 [2]:
[ 0.084265] ACPI: INT_SRC_OVR (bus 0 bus_irq 0 global_irq 2 dfl dfl)
[ 0.084266] ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 9 low level)
I'm not sure if it was IRQ 1 that needed to be overridden for that model
though, so it may work anyway with patch 2 of this series.
