Jakub,

Digging a bit further, it looks like the 8188EU, 8192EU, and 8723BU, use
a different RF module than the previous parts. They have far more RF
registers, so the code for reading/writing RF registers does not work as
is.

Hopefully shouldn't be too hard to fix, but it also mean that the RF
init table used for the older parts will not match whats needed for the
new parts.
