[U-Boot] [PATCH v2 25/55] x86: Bring up northbridge, pch and lpc after the CPUs

[Simon Glass]

These devices currently need to be inited early in boot. Once we have the
init in the right places (with each device doing its own init and no
problems with ordering) we should be able to remove this. For now it is
needed to keep things working.

Changes in v2:
- Add a comment as to why we are initing the devices again
