soc/amd/*/include/msr: add version number to SERIAL_VID_* define names
Picasso and Cezanne use the serial voltage ID 2 standard to communicate
the CPU voltage to the voltage regulator module on the mainboard, while
Mendocino, Phoenix and Glinda use the serial voltage ID 3 standard for
this. Both standards encode the voltage in a different way, so add the
serial VID version number to the defines to clarify for which version
the define is.
