net: ethernet: bgmac: add dma_dev pointer
The dma buffer allocation, etc references a dma_dev device pointer from
the bcma core. In anticipation of removing the bcma requirement for
this driver, these must be changed to not reference that struct. Add a
dma_dev device pointer to the bgmac stuct and reference that instead.
