nb/intel/sandybridge: Drop iommu.c and rename functions

* Move the contents of iommu.c to early_init.c.
* Name the functions like done in intel/soc/common.
* Move PAMx register setup to own function

Preparations for integration in soc/intel/common/*

Tested on Lenovo T520 (Intel Sandy Bridge).
Still boots to OS, no errors visible in dmesg.
