Subject: [PATCH] ACPI: resource: do IRQ override on Lenovo 14ALC7

Commit bfcdf58380b1 ("ACPI: resource: do IRQ override on LENOVO IdeaPad")
added an override for Lenovo IdeaPad 5 16ALC7. The 14ALC7 variant also
suffers from a broken touchscreen and trackpad.

Fixes: 9946e39fe8d0 ("ACPI: resource: skip IRQ override on AMD Zen platforms")
Link: https://bugzilla.kernel.org/show_bug.cgi?id=216804
