Arnd Bergmann a5e4bd9913 of_mdio: select fixed phy support unconditionally
Calling the fixed-phy functions when CONFIG_FIXED_PHY=m as a previous
change tried cannot work if the caller is in built-in code:

drivers/of/built-in.o: In function `of_phy_register_fixed_link':
of_reserved_mem.c:(.text+0x85e0): undefined reference to `fixed_phy_register'

Making of_mdio depend on 'FIXED_PHY || !FIXED_PHY' would solve this
dependency by enforcing that OF_MDIO itself becomes a loadable module
when FIXED_PHY=y, but that creates a different dependency as it
breaks any built-in ethernet driver that uses of_mdio.

Making FIXED_PHY a bool option also cannot work, since it depends on
PHYLIB, which again is tristate.

This version now uses 'select FIXED_PHY' to ensure that the fixed-phy
portion of of_mdio is not optional. The main downside of this is
a small increase in code size for cases that do not need fixed phy
support, but it should avoid all of the link-time problems.
