[PATCH] realtek: Fix kernel dependencies on CONFIG_MDIO_SMBUS

[Hauke Mehrtens]

CONFIG_SFP depends on CONFIG_MDIO_SMBUS now and this depends on
CONFIG_I2C_SMBUS. Activate the missing kernel compile options.

This fixes the following warning:
WARNING: unmet direct dependencies detected for MDIO_SMBUS
  Depends on [n]: NETDEVICES [=y] && MDIO_DEVICE [=y] && MDIO_BUS [=y] && I2C_SMBUS [=n]
  Selected by [y]:
  - SFP [=y] && NETDEVICES [=y] && PHYLIB [=y] && I2C [=y] && PHYLINK [=y] && (HWMON [=y] || HWMON [=y]=n)

Fixes: 45053b507c66 ("realtek: Add support for SFP EEPROM-access over SMBus")
