Bora Guvendik 860672e987 soc/intel/alderlake: Inject CSE TS into CBMEM timestamp table

Get boot performance timestamps from CSE and inject them into CBMEM
timestamp table after normalizing to the zero-point value. Although
consumer CSE sku also supports this feature, it was validated on
CSE Lite sku only.

TEST=Able to see TS elapse prior to IA reset on Brya/Redrix
