Rafał Miłecki 6d3fbf2818 kernel: backport simple bgmac cleanup & fix from Jon 
These 2 trivial patches will be followed by a bigger bgmac rework so
they are worth backporting in a separated patch.

Subject: [PATCH 1/5] net: ethernet: bgmac: change bgmac_* prints to dev_*
prints
The bgmac_* print wrappers call dev_* prints with the dev pointer from
the bcma core. In anticipation of removing the bcma requirement for
this driver, these must be changed to not reference that struct. So,
simply change all of the bgmac_* prints to their dev_* counterparts. In
some cases netdev_* prints are more appropriate, so change those as
well.
