[PATCH 08/20] ARM: dts: imx6q-dhcom: Fill GPIO line names on DHCOM SoM

[Christoph Niedermaier]

Fill in the custom GPIO line names used by DH on the DHCOM SoM.
The GPIO line names are in accordance to DHCOM Design Guide R04
available at [1], section 3.9 GPIO. Adding also GPIO line names
for the hardware and memory coding.
