I do not see how the bcma driver [bgmac-bcma.c] will no longer work.
The whole idea behind introducing this  BGMAC_FEAT_IDM_MASK bit
was to keep bcma driver's functionality intact.

The BGMAC_FEAT_IDM_MASK bit is explicitly set by the bgmac-platform driver
and is unset inside the same if the idm register base is provided.

For BCMA driver case, I do not touch BGMAC_FEAT_IDM_MASK bit, i.e. it
is *not* set.
And if it is not set, each idm operation done in bgmac.c will take place.
Please explain if I am missing something here.

Abhishek
