Tony Lindgren 6469b2fead ARM: dts: ti: omap: Fix bandgap thermal cells addressing for omap3/4
Fix "thermal_sys: cpu_thermal: Failed to read thermal-sensors cells: -2"
error on boot for omap3/4. This is caused by wrong addressing in the dts
for bandgap sensor for single sensor instances.

Note that omap4-cpu-thermal.dtsi is shared across omap4/5 and dra7, so
we can't just change the addressing in omap4-cpu-thermal.dtsi.
