Change subject: Add Tiger Lake U Premium support ......................................................................
Add Tiger Lake U Premium support
Tiger Lake has very low ICCRIBA (TGL=0x11, CNL=0x34 and CML=0x34) and detects as unknown chipset compatible with 300 series chipset. Add a new enum CHIPSET_500_SERIES_TIGER_POINT and treat it identically to CHIPSET_400_SERIES_COMET_POINT. There are some exceptions though, ICCRIBA is no longer present n descriptor content so a new union has been defined for new fields and used in descriptor guessing. freq_read field is not present on Tiger Lake, moreover in CannonPoint and Comet Point this field is used as eSPI/EC frequency, so a new function to print read frequency has ben added. Finally Tiger lake boot straps include eSPI, so a new bus has been added for the new straps.
TEST=Flash BIOS region on Intel i5-1135G7
