As-is, this leads to a failure to build on ls1012aqds_tfa_SECURE_BOOT
and a number of other platforms.  For v3, please throw this at CI,
either in Azure or GitLab via the clock tree, thanks.

In specifics, I've thrown this and the fls/ffs series at my lab and it
seems to cause mx6cuboxi to fail to boot (a Pi 3 in 32bit mode, and
am335x_evm are booting fine as are the Pi 3 in 64bit mode, libretech-cc,
pine64_plus, am65x_evm_a53, and j721e_evm_a72).  I did a size comparison
build again and the whole log is at:
https://gist.github.com/trini/2e88e94743821586ef742a936c45c389
as there's some oddities again (like SPL growing).
