[RFC][PATCH] b43: drop Kconfig option of forcing PIO mode

[Rafał Miłecki]

We have module param called use_pio which is much easier to use.

Larry introduced use_pio with:
    b43: Allow PIO mode to be selected at module load
I believe we can leave this simple module param and drop
CONFIG_B43_FORCE_PIO instead.
