[PATCH -next] alpha: lib: Export __delay

[Guenter Roeck]

__delay is exported by most architectures, and may be used in modules.
Since it is not exported for alpha, alpha builds currently fail
to build in -next with

ERROR: "__delay" [drivers/net/phy/mdio-octeon.ko] undefined!

if the offending driver is configured.

Fixes: a6d678645210 ("net: mdio-octeon: Modify driver to work on both
	ThunderX and Octeon")
