Rework imx_thermal driver to be used across i.MX
processor that support thermal sensor

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.
Changes for V3:
Rework path for git://git.denx.de/u-boot-imx.git (master)
