cpu/x86: Make MP init timeout configurable

The current MP init timeout is hardcoded as 1s. To support
platform with many cpus, the timeout needs to be adjusted.
The number of cpus is calculated as:
number of sockets * number of cores per socket *
  number of threads per core

How long the timeout should be set to, is heuristic.
It needs to be set long enough to ensure reboot stability,
but not unreasonable so that real failures can be detected
soon enough, especially for smaller systems.

This patch sets timeout to be minimum as 1 second, while each
cpu adds 0.1 second.
