Bug Description
[Impact]
After system sleep, Goodix touchpad doesn't work anymore.
[Fix]
Add a delay after issuing SET_POWER_ON command.
[Test]
With the patch applied, Goodix touchpad still works after system sleep.
[Regression Potential]
The original delay between SET_POWER_ON and RESET was increaed to 60ms,
so the the driver becomes much more forgiving on power management. Hence
I am not seeing any major potential regression risk here.
