ACPI: resource: do IRQ override on LENOVO IdeaPad
LENOVO IdeaPad Flex 5 is ryzen-5 based and the commit below removed IRQ
overriding for those. This broke touchscreen and trackpad:
i2c_designware AMDI0010:00: controller timed out
i2c_designware AMDI0010:03: controller timed out
i2c_hid_acpi i2c-MSFT0001:00: failed to reset device: -61
i2c_designware AMDI0010:03: controller timed out
...
i2c_hid_acpi i2c-MSFT0001:00: can't add hid device: -61
i2c_hid_acpi: probe of i2c-MSFT0001:00 failed with error -61
White-list this specific model in the override_table.
For this to work, the ZEN test needs to be put below the table walk.
