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.
