Pull DeviceTree updates from Rob Herring:
- fix sparse warnings in drivers/of/
- add more overlay unittests
- update dtc to
v1.4.4-8-g756ffc4f52f6. This adds more checks on dts
files such as unit-address formatting and stricter character sets for
node and property names
- add a common DT modalias function
- move trivial-devices.txt up and out of i2c dir
- ARM NVIC interrupt controller binding
- vendor prefixes for Sensirion, Dioo, Nordic, ROHM
- correct some binding file locations

otherwise full reconfiguration is done.
- external-fpga-config : boolean, set if the FPGA has already been configured
prior to OS boot up.
+- encrypted-fpga-config : boolean, set if the bitstream is encrypted
- region-unfreeze-timeout-us : The maximum time in microseconds to wait for
bridges to successfully become enabled after the region has been
programmed.
- region-freeze-timeout-us : The maximum time in microseconds to wait for
bridges to successfully become disabled before the region has been
programmed.
+ - config-complete-timeout-us : The maximum time in microseconds time for the
+ FPGA to go to operating mode after the region has been programmed.
- child nodes : devices in the FPGA after programming.
