cbfs: alternative support for cbfs_load_payload()
In certain situations boot speed can be increased by providing an
alternative implementation to cbfs_load_payload(). The
ALT_CBFS_LOAD_PAYLOAD option allows for the mainboard or chipset to
provide its own implementation.
Booted baskingridge board with alternative and regular
cbfs_load_payload().
