UPSTREAM: cpu/x86/mp_init: Increase AP check-in time-out to 1second
Currently, the AP check-in time-out in bsp_do_flight_plan is set to
100ms. However, as the number of APs increases, contention could
increase especially for resource like UART. This led to MP record
time-out issues on KBL platform with 7 APs and serial-console enabled
BIOS image.
This change increases the time-out value to 1 second to be on the safer
side and let APs check-in before continuing boot.
BUG=b:74085891
TEST=Verified that MP record time-out is not observed anymore on Nami.
