[PATCH 6/6] DO NOT MERGE: full sensehat device tree overlay for raspberry pi 4

This patch shold not be merged - dtbs files are not stored in the
kernel tree. We just provide this file so the code can be tested.

This overlay is suitable for testing the driver, it can be compiled with
dtc and put in the /boot/overlays/ folder then specified in config.txt
by putting the lines:

dtoverlay=		#suppress loading of default overlay for HAT
dtoverlay=sensehat	#load custom overlay

at the beginning before any other lines in config.txt
