ARM: dts: msm: Add device tree for APQ8096 drone platform

Adds the devicetree for the 8096 drone platform. This platform is
different than other msm8996 platform in that it has no display panel or
touch support. There is no NFC or pcie1/2 bus support. Wifi is supported
with rome and a number of SPI/I2C/UART buses have been made available
for controlling flight and sensor functionality. A sensor file has been
added in case users wish to enable sensor controls from the apps
processor instead of SLPI.
