cbfs: Allow CBFS to be used in SPL

Add a new Kconfig option to enable CBFS in SPL. This can be useful when
the memory-init code is in CBFS.

help
Define this to enable support for reading from a Coreboot
filesystem. This is a ROM-based filesystem used for accessing files
on systems that use coreboot as the first boot-loader and then load
U-Boot to actually boot the Operating System.
Note that most functions in the CBFS API do not work with SPL. Only
those which accept a cbfs_priv * can be used, since BSS is not
available.
