Subject: [PATCH] ACPI: resource: Skip IRQ override on Asus Expertbook B2402CBA

Like the Asus Expertbook B2502CBA and various Asus Vivobook laptops,
the Asus Expertbook B2402CBA has an ACPI DSDT table that describes IRQ 1
as ActiveLow while the kernel overrides it to Edge_High. This prevents the 
keyboard from working. To fix this issue, add this laptop to the 
skip_override_table so that the kernel does not override IRQ 1.

This patch is very similar to 7203481fd12b1257938519efb2460ea02b9236ee
(ACPI: resource: Add Asus ExpertBook B2502 to Asus quirks) and just adds
another ExpertBook that has the same IRQ override problem to the quirks list.
