Atmel MXT touchscreen: increase reset timeouts
There is a more complete atmel patch-series out by Nick Dyer that fixes this and other things, but in the meantime this is the minimal thing to get the touchscreen going on (at least my) Pixel Chromebook. Not that I want my dirty fingers near that beautiful screen, but it seems that a non-initialized touchscreen will also end up being a constant wakeup source, so you have to disable it to go to sleep. And it's easier to just fix the initialization sequence. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
