stmmac: remove BUS_MODE_DA

This is a very old and often unused option to configure
a bit in a register inside the DMA. This support should
not stay under Koption and should be extended for new chips too.
This will be do later maybe via device-tree parameters.
Also no performance impact when remove this setting on STi platforms.

Selecting this option, rx has priority over Tx (only for Giga

By default, the DMA arbitration scheme is based on Round-robin
(rx:tx priority is 1:1).
