    cbfs: look for CBFS header in a predefined place
    
    This patch adds a facility to set the CBFS header offset. The offset
    value of zero means default. i.e. the CBFS initialization code still
    discovers the offset through the value saved at the top of the ROM.
    
    [pg: stripped to cover only the CBFS_HEADER_OFFSET memory region since
    CBFS diverged too much and will be worked on further in short order.]
