This patch forms composite module with i2c-sensor.c and new file
i2c-sensor-vid.c, which provides i2c_which_vrm function for detecting VRM
version of processor using cpuid_eax func. Resulting module has unchanged
name (i2c-sensor).

Before applaying this patch, please rename i2c-sensor.c to
i2c-sensor-detect.c
