    cs5536: add smbus support in ramstage
    With this patch it is possible to use the smbus in ramstage. The
    biggest part of the patch is a simple code split into a general
    part (smbus.h) and the concrete users (early_smbus.c and cs5536.c).
    After the switch from romstage to ramstage the smb base address
    has changed, but that is no problem as the new base address is
    stored in bar0 of the ISA bridge. It could also be read via msr,
    but via PCI it is simpler. I used the following patch as
    reference on how to readout the new base address:
