[PATCH v3 2/3] ACPI: resource: Always use MADT override IRQ settings for all legacy non i8042 IRQs

[Hans de Goede <hdegoede@redhat.com>]

All the cases, were the DSDT IRQ settings should be used instead of
the MADT override, are for IRQ 1 or 12, the PS/2 kbd resp. mouse IRQs.

Simplify things by always honering the override for other legacy IRQs
(for non DMI quirked cases).

This allows removing the DMI quirks to honor the override for
some non i8042 IRQs on some AMD ZEN based Lenovo models.

Changes in v2:
- Also do the ZEN check for IRQ 12 (Reported-by August Wikerfors)
- Move the gsi != 1 && gsi != 12 check to inside the #ifdef CONFIG_X86,
  this being the i8042 IRQs is X86 specific and the "return true;" is
  always done for #ifndef CONFIG_X86 already
