temp sensor: add support for G782
modify g781.c/.h to g78x.c/.h to suppor both G781/G782 temp sensor based on CONFIG_TEMP_SENSOR_G781 or CONFIG_TEMP_SENSOR_G782 BUG=none BRANCH=none TEST=make buildall; able to get temperature data on board with G782 Change-Id: Ia32c85e9964bfd7c0c5263f04368bc001a27fe10 Signed-off-by: Kevin K Wong <kevin.k.wong@intel.com> Reviewed-on: https://chromium-review.googlesource.com/334228 Reviewed-by: Shawn N <shawnn@chromium.org>
