ARM: dts: cm-t3x: add NAND support
CM-T3517, CM-T3530 and CM-T3730 features NAND storage chip connected to
GPMC bus.
Add GPMC DT entry into the root DT file omap3-cm-t3x.dtsi, common for
all three modules.
NAND timings are calculated to be safe for CM-T3x devices as it works
now in non DT boot (in this case the timings are updated by U-Boot).
Update GPMC ranges in boards DT files to include all connected devices.
