cbfs: Replace more instances of cbfs_boot_locate() with newer APIs

Browse Source 
In pursuit of the eventual goal of removing cbfs_boot_locate() (and
direct rdev access) from CBFS APIs, this patch replaces all remaining
"simple" uses of the function call that can easily be replaced by the
newer APIs (like cbfs_load() or cbfs_map()). Some cases of
cbfs_boot_locate() remain that will be more complicated to solve.
