realtek: mdio: fix non-debug SerDes builds

The new SerDes mdio driver produces the following compilation
error in non-debug builds.

drivers/net/mdio/mdio-realtek-otto-serdes.c:72:12:
error: 'rtsds_sds_to_mmd' defined but not used [-Werror=unused-function]
   72 | static int rtsds_sds_to_mmd(int sds_page, int sds_regnum)
      |            ^~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

Move the function into the debug section.
