This patch reorganises the internal stmmac ops structure.
The stmmac_ops has been splitted into other three structures named:
stmmac_ops
stmmac_dma_ops
stmmac_desc_ops
This makes the code more clear and also helps the next work to
make the driver more generic.

If NET_SKB_PAD is not a multiple of the cache line size, mv643xx_eth
allocates a couple of extra bytes at the start of each receive buffer
to make the data payload end up on a cache line boundary.
These extra bytes are skb_reserve()'d before DMA mapping, so they
should not be included in the DMA map byte count (as the mapping is
done starting at skb->data), nor should they be included in the
receive descriptor buffer size field, or the hardware can end up
DMAing beyond the end of the buffer, which can happen if someone
sends us a larger-than-MTU sized packet.
This problem was introduced in commit 7fd96ce47f ("mv643xx_eth:
rework receive skb cache alignment", May 6 2009), but hasn't appeared
to be problematic so far, probably as the main users of mv643xx_eth
all have NET_SKB_PAD == L1_CACHE_BYTES.

velocity_open() calls velocity_give_many_rx_descs(), which gives RX
descriptors to the NIC, before installing an interrupt handler or
calling velocity_init_registers(). I think this is very unsafe and it
appears to explain the bug report <http://bugs.debian.org/508527>.
On MTU change, velocity_give_many_rx_descs() is again called before
velocity_init_registers(). I'm not sure whether this is unsafe but
it does look wrong.
Therefore, move the calls to velocity_give_many_rx_descs() after
request_irq() and velocity_init_registers().

Since hibernation assumes power loss, we should fully reinitialize
PHYs (including platform fixups), as if PHYs were just attached.
This patch factors phy_init_hw() out of phy_attach_direct(), then
converts mdio_bus to dev_pm_ops and adds an appropriate restore()
callback.

Here is why.
On suspend:
- PM core starts suspending devices, ucc_geth_suspend gets called;
- ucc_geth calls phy_stop() on suspend. Note that phy_stop() is
mostly asynchronous so it doesn't block ucc_geth's suspend routine,
it just sets PHY_HALTED state and disables PHY's interrupts;
- Suddenly the state machine gets scheduled, it grabs the phydev->lock
mutex and tries to process the PHY_HALTED state, so it calls
phydev->adjust_link(phydev->attached_dev). In ucc_geth case
adjust_link() calls msleep(), which reschedules the code flow back to
PM core, which now finishes suspend and so we end up sleeping with
phydev->lock mutex held.
On resume:
- PM core starts resuming devices (notice that nobody rescheduled
the state machine yet, so the mutex is still held), the core calls
ucc_geth's resume routine;
- ucc_geth_resume restarts the PHY with phy_stop()/phy_start()
sequence, and the phy_*() calls are trying to grab the phydev->lock
mutex. Here comes the deadlock.
This patch fixes the issue by stopping the state machine on suspend
and starting it again on resume.

We've long lacked a good confirmation that frames
have really gone out, e.g. before going off-channel
for a scan. Add a flush() operation that drivers
can implement to provide that confirmation, and use
it in a few places:
* before scanning sends the nullfunc frames
* after scanning sends the nullfunc frames, if any
* when going idle, to send any pending frames

It is checked in add_interface, but there it is easily replaced with
a check of priv->vif. If that information should become necessary,
it is available in vif->type anyway.
It is also checked in led_turn_on and led_turn_off, where I made the
substitutions as described above. Of course, these checks seem to
have been incorrect since the driver was using NL80211_IFTYPE_MONITOR
to indicate no interface rather than NL80211_IFTYPE_UNSPECIFIED.
Anyway, I think these checks may be extraneous...?

rt2800lib currently checks whether RT2800USB is enabled in the configuration.
Strictly speaking this is not necessary, it only needs to know whether the
generic rt2x00usb library functions are available. Therefore check for
