net: miiphybb: configs: Drop CONFIG_BITBANGMII_MULTI

It seems that every remaining system which enables BITBANGMII also
enables BITBANGMII_MULTI . Remove the BITBANGMII_MULTI symbol and
assume it is always enabled. This allows removal of a bit of legacy
code. No functional change intended.

-If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs

-
-MII_INIT      - Generic code to enable the MII bus (optional)
-MDIO_DECLARE  - Declaration needed to access to the MDIO pin (optional)
-MDIO_ACTIVE   - Activate the MDIO pin as out pin
-MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin
-MDIO_READ     - Read the MDIO pin
-MDIO(v)       - Write v on the MDIO pin
-MDC_DECLARE   - Declaration needed to access to the MDC pin (optional)
-MDC(v)	      - Write v on the MDC pin
-
-The previous macros make the driver compatible with the previous version
-(that didn't support the multi-bus).
 
-When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill
-the bb_miiphy_buses[] array with a record for each required bus and declare
