[ Upstream commit 05cda427126f30ce3fc8ffd82fd6f5196398d502 ]

Like the ASUS ExpertBook B2502CBA and various ASUS Vivobook laptops, the
ASUS ExpertBook B1502CBA has an ACPI DSDT table that describes IRQ 1 as
ActiveLow while the kernel overrides it to Edge_High.

$ sudo dmesg | grep DMI
DMI: ASUSTeK COMPUTER INC. ASUS EXPERTBOOK B1502CBA_B1502CBA/B1502CBA, BIOS B1502CBA.300 01/18/2023
$ grep -A 40 PS2K dsdt.dsl | grep IRQ -A 1
IRQ (Level, ActiveLow, Exclusive, )
{1}

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.
