[coreboot-gerrit] Change in coreboot[master]: cbfs: Move more stuff into cbfs_boot_lookup()

[Julius Werner (Code Review)]

Hello Philipp Deppenwiese, build bot (Jenkins), Patrick Georgi, Aaron Durbin,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/39327

to look at the new patch set (#8).

cbfs: Move more stuff into cbfs_boot_lookup()

cbfs_boot_locate() is supposed to be deprecated eventually, after slowly
migrating all APIs to bypass it. That means common features (like
RO-fallback or measurement) need to be moved to the new
cbfs_boot_lookup().

Also export the function externally. Since it is a low-level API and
most code should use the higher-level loading or mapping functions
instead, put it into a new <cbfs_private.h> to raise the mental barrier
for using this API (this will make more sense once cbfs_boot_locate() is
removed from <cbfs.h>).
