cbfs: look for CBFS header in a predefined place

This patch introduces a new option (CONFIG_MULTIPLE_CBFS_INSTANCES) to
    allow multiple CBFS instances in the bootrom.

When the new option is enabled, the code running on the target
    controls which CBFS instance is used. Since all other then header CBFS
    structures use relative addressing, the only value which needs
    explicit setting is the offset of the CBFS header in the bootrom.

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.

BRANCH=storm
    BUG=chrome-os-partner:34161, chromium:445938
    TEST=with the rest patches in, storm target successfully boots from RW
         section A.
