[PATCH 2/2] ARM: dts: imx6sll: Add the Kobo Aura H2O Edition 2

[Denis 'GNUtoo' Carikli <GNUtoo@cyberdimension.org>]

This work is based on the devicetree that can be found
in the source code published by the device vendor[1],
and on testing on the hardware as not all the parts
described in the vendor's imx6sll-e60qm2.dts are populated
on the PCB.
