Alan Luck 4c1d7787d4 ipq806x: Add buttons to OnHub 
These are the factory reset button (external) and "developer mode"
button (hidden inside the case (ASUS) or under a screw in the base
(TP-Link)) found on the TP-Link and ASUS OnHub devices.

Signed-off-by: Alan Luck <luckyhome2008@gmail.com>
[Brian: add description; factor out for both ASUS and TP-Link; use
existing pinmux definitions; add keycode for dev button]
