intel/sandybridge: Don't hardcode platform type
* Add a function to return CPU platform ID bits
* Add a function to return platform type
** Platform id is 4 on Lenovo T430 (mobile)
** Platform id is 1 on HP8200 (desktop)
* Use introduced method to handle platform specific code
* Use enum for platform type
* Report platform ID
