rt2x00: convert rt2*_bbp_read return type

This is a semi-automated conversion to change *_bbp_read()
to return the register contents instead of passing them by value,
resulting in much better object code. The majority of the patch
was done using:

sed -i 's:\(\<rt.*_bbp_read\>(.*, .*\), &\(.*\));:\2 = \1);:' \
    -i 's:\(\<rt.*_bbp_dcoc_read\>(.*, .*\), &\(.*\));:\2 = \1);:' \
    -i 's:= _\(rt.*_bbp_read\):\1:' drivers/net/wireless/ralink/rt2x00/*
