pci_ids.h --- Added new ids.

boot.c  -- Modified to compile even with -fPIC
generic_sdram.inc -- split out generic_sdram_enable.inc -- Some chipsets
    don't need that enable logic.
Added serial_fill_inbuf.c
Removed unused 440gx/param.h sis/630/param.h
Modified: make.base crt0.base ldscript.base mainboard/Config and NLBConfig.py

In NLBConfig.py added the directive mainboardinit (a variant of raminit.inc)
  This allows us to remove hardcodes in crt0.S updated every mainboard/Config to
  reflect the current state of the hardcodes, and the split of generic_sdram.inc
  In crt0.S we should have the bare minimum code in assembly needed to get to C code.

mkrom is no longer needed.
