lib/prog_loaders, soc/amd/: Make payload_preload use cbfs_preload
Now that CBFS has this functionality built in, we no longer need to
manually code it.
payload_preload used to use the payload_preload_cache region to store
the raw payload contents. This region was placed outside the firmware
reserved region, so it was available for use by the OS. This was
possible because the payload isn't loaded again on S3 resume.
cbfs_preload only uses the cbfs_cache region. This region must be
reserved because it gets used on the S3 resume path. Unfortunately this
means that cbfs_cache must be increased to hold the payload. Cezanne is
the only platform currently using payload_preload, and the size of
cbfs_cache has already been adjusted.
In the future we could look into adding an option to cbfs_preload that
would allow it to use a different memory pool for the cache allocation.
BUG=b:179699789
TEST=Boot guybrush and verify preloading the payload was successful
CBFS DEBUG: get_preload_rdev(name='fallback/payload') preload successful
