Michael Buesch 36dbd9548e b43: Use a threaded IRQ handler
Use a threaded IRQ handler to allow locking the mutex and
sleeping while executing an interrupt.
This removes usage of the irq_lock spinlock, but introduces
a new hardirq_lock, which is _only_ used for the PCI/SSB lowlevel
hard-irq handler. Sleeping busses (SDIO) will use mutex instead.

Michael Buesch fb11137af8 b43: Split PHY alloc and init
This splits the PHY allocation from the PHY init.
This is needed in order to properly support Analog handling.

Michael Buesch 99c4a78062 b43: Move remaining code from phy.c to phy_a.c
This moves the remaining code from phy.c to phy_a.c
phy.c is removed.
No functional change. Just moving code and removing dead code.

Michael Buesch 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.

Michael Buesch 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.
