Subject: [PATCH v2 06/11] ARM: dts: imx6ul-kontron-n6x1x-s: Specify bus-width
 for SD card and eMMC

From: Frieder Schrempf <frieder.schrempf@...tron.de>

Both, the SD card and the eMMC are connected to the usdhc controller
by four data lines. Therefore we set 'bus-width = <4>' for both
interfaces.
