[PATCH] of/mdio: fix build errors when CONFIG_OF isn't set

[Sasha Levin <sasha.levin@oracle.com>]

Commit f9dc9ac5 ("of/mdio: Add dummy functions in of_mdio.h.") has added
empty stubs into of_mdio.h which were not static, this causes build errors
when these symbols were defined across several objects.

Fix it by marking those stubs as 'static inline'.
