nb/intel/haswell/pei_data.h: Add ULT system type

Looks like 5 is a valid system type, as Google Beltino and Slippy are
using it. According to comments on these mainboards' code, this value
corresponds to ULT systems. So, add it to the comment on the pei_data
struct, which was likely copied from Sandy Bridge and was not updated.
