We want to be able to share data between different phases of firmware
(rom stage/ram stage/payload). Coreboot CBMEM seems an appropriate
location for this data, but normally it is not initialized
until coreboot reaches the ram stage.
This change initializes the CBMEM while still in rom stage in
case CONFIG_EARLY_CBMEM_INIT is set.
Note that there is a discrepancy in how coreboot determines the
size of DRAM at rom and ram stages, get_top_of_ram() is used at
rom stage and is not defined for all platforms. Those platforms
will have to define this function should they enable the
CONFIG_EARLY_CBMEM_INIT flag.

Only the BSP CPU was able to start its hyper-threading CPU siblings.
When an AP CPU attempts this it calls start_cpu() within start_cpu(),
deadlocking the system with start_cpu_lock.
At the time intel_sibling_init() is run, the BSP CPU is still
walking the cpu_bus linked list in lapic_cpu_init: start_other_cpus().
A sibling CPU appended at the end of this list will get started.
Also fail compile with #error if SERIAL_CPU_INIT==0, as microcode
updates on hyper-threading sibling CPUs must be serialized.
