Merge tag 'omap-for-v3.20/dm816x-data' into for-next

Patches to add necessary SoC related clockdomain and interconnect
data  to make dm816x boot with basic devices. This finally gets
dm816x into a usable shape for further work to happen after a few
years of stalled effort of making this SoC to work with the mainline
kernel.

As most of the devices are similar to the other omap variants, we
get at least serial, MMC, Ethernet, I2C, EDMA, pinctrl, SPI and GPMC
working for these SoCs with the related device tree changes.
