ARM: dts: pcduino: Enable user LED and button support for pcDuino
The pcDuino board has LEDs connected to PH15/PH16, and back/home/menu
buttons to PH17/18/19 respectively. Enable these via gpio-leds and
gpio-keys. This is shared across the v1 and v2 versions of the board.
Tested on a v2 and verified against the schematics of a v1.

[Maxime: Added some newlines between the button nodes]
