UPSTREAM: Revert "Revert "drivers/intel/fsp2_0: Allow `mp_startup_all_cpus()` to run serially""

This reverts a change that was causing hangs and exceptions during boot
on an ADL brya4es.

The hang (or APIC exception) occurs at what appears to be the FSP MP
initialization sequence, prior to the "Display FSP Version Info HOB"
log being displayed :

  [DEBUG]  Detected 10 core, 12 thread CPU.
  [DEBUG]  Display FSP Version Info HOB

This reverts commit 40ca79714ad7d5f2aa201d83db4d97f21260d924.

BUG=b:224873032
TEST=`emerge-brya coreboot chromeos-bootimage`, flash and verify brya4es
is able to successfully reboot 200 times without any issues.

(cherry picked from commit 1abbb96c36978b5af167c0ed682403a48f32ab05)
