MLK-12140 ARM: dts: imx7d-sdb-epdc: add EPDC touch support for imx7d-sdb
EPDC board has touch screen, this patch add touch support on imx7d-sdb TO1.1
board, due to the touch pin conflict with UART5 and GPMI, so disable UART5 in
imx7d-sdb-epdc.dtsi. For GPMI, it default disabled in imx7d-sdb.dts, so do not
impact touch.
