b43: Add NPHY kconfig option
This adds a new Kconfig option for enabling probing of N-PHYs.
This option will be removed again once the stuff works.
For now it is to help in development. This way real users won't
execute the broken N-PHY codepaths, but the developers can easily
enable N-PHY stuff.
To enable N-PHY probing simply remove the BROKEN dependency
and enable the option in the kernel config.

Remove b43 PIO support.
DMA works well on all supported devices. There's no reason to use PIO.
Additionally, new devices don't support PIO in hardware anymore.
b43 PIO support is dead and unused code.
After applying this patch please do

ntohs(read(&p->mrx_overflow)
