Add Tiger Lake U Premium support

Tiger Lake has very low ICCRIBA (TGL=0x11, CNL=0x34 and CML=0x34) and
detects as uknown 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 except the ICCRIBA in descriptor
guessing, pprint_freq and boot straps.

TEST=Flash BIOS region on Intel i5-1135G7
