HID: i2c-hid: Revert to using power commands to wake on resume
commit 7d6f065de37c ("HID: i2c-hid: Use address probe to wake on resume") replaced the retry of power commands with the dummy read "bus probe" we use on boot which accounts for a necessary delay before retry. This made at least one Weida device (2575:0910 in an ASUS Vivobook S14) very unhappy, as the bus probe despite being successful somehow lead to the following power command failing so hard that the device never lets go of the bus. This means that even retries of the power command would fail on a timeout as the bus remains busy. Remove the bus probe on resume and instead reintroduce retry of the power command for wake-up purposes while respecting the newly established wake-up retry timings.
