drivers/wifi: Drop maxsleep parameter from chip config
This change drops maxsleep parameter from chip config and instead
hardcodes the deepest sleep state from which the WiFi device can wake
the system up from to SLP_TYP_S3. This is similar to how other device
drivers in coreboot report _PRW property in ACPI. It relieves the
users from adding another register attribute to devicetree since all
mainboards configure the same value. If this changes in the future, it
should be easy to bring the maxsleep config parameter back.
