[PATCH 2/9] dsa: mv88e6xxx: hide unused functions

[Arnd Bergmann <arnd@arndb.de>]

When CONFIG_NET_DSA_HWMON is disabled, we get warnings about two unused
functions whose only callers are all inside of an #ifdef:

drivers/net/dsa/mv88e6xxx.c:3257:12: 'mv88e6xxx_mdio_page_write' defined but not used [-Werror=unused-function]
drivers/net/dsa/mv88e6xxx.c:3244:12: 'mv88e6xxx_mdio_page_read' defined but not used [-Werror=unused-function]

This adds another ifdef around the function definitions. The warnings
appeared after the functions were marked 'static', but the problem
was already there before that.

When I first submitted it on June 23, there was a clash with some
other patches, this version is based on top of current mainline,
which contains those patches already, so it should apply cleanly.
