ARM: dts: am3517-evm: Add LCD panel type 15 support
The AM3517-EVM by Logic PD has a Logic PD type 15 display LCD attached to the baseboard, and the SOM itself has an integrated touchscreen controller. This patch enables both the LCD and the tsc2004 on the SOM. Signed-off-by: Adam Ford <aford173@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
