soc/intel/tgl: Add configurable value for ConfigTdpLevel
According to Tigerlake TDP specifications (doc #575683, table 4-2),
TGL supports different TDP levels depends on CPU segement/package,
IA Cores and graphics configuration. For example, UP3 4-Core GT2
suppots base TDP=28W, Configurable TDP-Down_1=15W and Configurable
TDP-Down_2=12W. This configurable value can be used to select
suitable TDP level
