__delay is exported by most architectures, and may be used in modules.
Since it is not exported for s390, s390:allmodconfig currently fails
to build with
ERROR: "__delay" [drivers/net/phy/mdio-octeon.ko] undefined!
Fixes: a6d678645210 ("net: mdio-octeon: Modify driver to work on both
ThunderX and Octeon")
