Rework imx_thermal driver to be used across i.MX processor that support thermal sensor
Signed-off-by: Adrian Alonso aalonso@freescale.com Signed-off-by: Peng Fan Peng.Fan@freescale.com --- Changes for V2: Rename read_cpu_temperature to read_cpu_temperature_mx6 use is_soc_type macro to identify iMX SoC family to call the correspondind read_cpu_temperature function per iMX SoC family
Patch dependency imx: arch-mx6: add is_soc_type helper macro
