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.
BUG=b:182575295
TEST=Able to see TS elapse prior to IA reset on Brya/Redrix
990:CSME ROM started execution 0
944:CSE sent 'Boot Stall Done' to PMC 88,000
945:CSE started to handle ICC configuration 88,000 (0)
946:CSE sent 'Host BIOS Prep Done' to PMC 90,000 (2,000)
947:CSE received 'CPU Reset Done Ack sent' from PMC 282,000 (192,000)
0:1st timestamp 330,857 (48,857)
11:start of bootblock 341,811 (10,953)
12:end of bootblock 349,299 (7,487)
