In the ACPI DSDT table for Asus VivoBook K3402ZA/K3502ZA
IRQ 1 is described as ActiveLow; however, the kernel overrides
it to Edge_High. This prevents the internal keyboard from working
on these laptops. In order to fix this add these laptops to the
skip_override_table so that the kernel does not override IRQ 1 to
Edge_High.
