Now, there are only two functions to send a host command:
* send_cmd that receives a iwl_host_cmd
* send_cmd_pdu that builds the iwl_host_cmd itself and received flags

The flags CMD_ASYNC / CMD_SYNC / CMD_WANT_SKB are not changed by the API
functions.

Kill the unused flags CMD_SIZE_NORMAL / CMD_NO_SKB on the way.

Tx free functions move to the transport layer. Unify the functions that deal with tx queues and cmd queue.

Since the CMD queue is not fully allocated, but uses the q->n_bd / q->window trick, the release flow of TX queue and CMD queue was different.
iwlagn_txq_free_tfd receives now the index of the TFD to be freed, which allows to unify the release flow for all the queues.

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
Author: Wey-Yi Guy <wey-yi.w.guy@intel.com>
Date:   Thu May 6 08:54:11 2010 -0700

    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.
