Move some PCI functionality to the new iwl_pci.[ch] files:
* the PCI_DEVICE_TABLE
* the pci_driver struct definition
* the PCI probe / remove functions
* the PCI suspend / resume functions

All these functions are now split: the trigger comes from the PCI layer which
calls to the bus generic code located in the other files.

This is the beginning only. There are still a lot of PCI related code needs
to be gathered.

We use priv->mutex to avoid race conditions between iwl_chswitch_done()
and iwlagn_mac_channel_switch(), when marking channel switch in
progress. But iwl_chswitch_done() can be called in atomic context
from iwl_rx_csa() or with mutex already taken from iwlagn_commit_rxon().

These bugs were introduced by:

commit 79d07325

    iwlwifi: support channel switch offload in driver

To fix remove mutex from iwl_chswitch_done() and use atomic bitops for
marking channel switch pending.

Also remove iwl2030_hw_channel_switch() since 2000 series adapters are
2.4GHz only devices.

If a device error happens while the uCode is
being loaded or initialised, we will attempt
to restart the device (which will likely fail
again, but that's not the issue here). During
this new restart, we turn off the device, but
as the uCode failed to initialise it already
is turned off. As a consequence, grabbing NIC
access will fail and cause excessive messages
and hangs.

To fix this issue, introduce a new status bit
and only attempt to reprogram the device when
it isn't already disabled.

There's no need to keep both normal and BT statistics
versions around all the time in memory when we only
use a subset of both. So keep only the subsets that
we need in memory, depending on the debug config).

Also, in doing so, we can remove all the calls to
iwl_bt_statistics() in the driver as we'll just
access the copied statistics now.

Finally, also remove this call from the one place
where it might still be needed and automatically
detect what kind of statistics the device is sending
based on their size. This way, we don't need to keep
track of which devices do what any more, which is
good since this is subject to change based on the
ucode version (as some ucode even for non-BT devices
will in fact use BT statistics).

Warn upon encountering a statistics command from the
ucode that isn't known, so we will find such issues
earlier in the future.

we took before will quickly make things harder to

The ucode restart has to take into account a number
of things, like clearing the HCMD_ACTIVE and other
status bits, and waking up the wait_command_queue.
Currently, however, there are a number of places
that neither do that, nor actually set the FW error
bit that leads to proper restart handling, which
means that in those cases things will probably just
hang completely.

To clean this up, make all ucode restart go through
a single function, except for the cases where it's
called during firmware loading.

Also fix a bug in wimax coexist restart avoidance,
it needs to first clear the status bits (and it has
to clear the HCMD_ACTIVE one as well) and then wake
up anything waiting on wait_command_queue.
