The driver has a set of different initvals for 20 MHz
vs dynamic HT2040 operation. Because we can't change
some of the registers "in-flight", the driver needs to
perform a warm reset.

Ever since carl9170 gained support to read the noisefloor,
the reported noisefloor level was pretty poor.
Initially I assumed that something was wrong in the PHY
setup and it would be impossible to fix without any
guidances. But this was not the case. In fact the nf
readings were correct and the thing that was broken
was the "simple" sign extension code!

Why not use it instead of the generic initval default?
