ASoC: wsa883x: disable speaker brown out protection 



Disable brown out protection (bop) attenuation levels 1,2 and 3 
which causes fast and coarse transitions in gain during voltage drop.
This creates "pop" noise during the drop. Since battery current
limiting (bcl) feature is enabled with CPS, bop is redundant and
can be disabled.
