[ Upstream commit 6469b2feade8fd82d224dd3734e146536f3e9f0e ] 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.
