fa9abe050d b43: Don't use memcpy for overlapping areas
It is valid to pass &gphy->rfatt and &gphy->bbatt as rfatt and bbatt
pointer arguments to the function. So we have to use memmove for the
possibly overlapping memory areas.

18c8adeb02 b43: Rewrite TX power adjustment
This patch rewrites the TX power recalculation algorithms to scale better
with changed enviromnent. If there's low
TX traffic, the power will be checked against the desired values
every 60 seconds.
If there is high TX traffic, the check is redone every 2 seconds. This improves
the reaction times a lot and confuses the rate control less.
It will also reduce the time it initially takes to tune to a new TX power
value. With the old algorithm it could take about 30 to 45 seconds to settle to
a new power value. This will happen in about two to four seconds now.

ef1a628d83 b43: Implement dynamic PHY API
This patch implements a dynamic "ops" based PHY API.
This is needed in order to conveniently support future PHY types
to avoid the "switch"-hell.

This patch does not change any functionality. It just moves lots
of code from one place to another and adjusts it for the changed
data structures.
