Default to MAX_UCODE_BEACON_INTERVAL if the output of
iwl_adjust_beacon_interval would otherwise be zero.  This prevents a
division by zero on my iwl5300-equipped Lenovo T400 with kernels that
include "mac80211: use cfg80211s BSS infrastructure".

This patch is a bit of a hack -- I'm not sure why iwl_setup_rxon_timing
is giving iwl_adjust_beacon_interval a zero input (which is the only way
it would output zero).  I would be happy to have a better fix.  But for
now, this makes my box boot...

Fixes:
- iwlwifi is an optional driver and should thus not default to 'y'.
- 3945 now depends on IWLCORE.

Rework:
- There is not a case when IWLCORE should not be selected. At the same time
  the driver does not use IWLWIFI or IWLCORE. We can just merge the usage of
  these two. With IWLWIFI being the driver name we proceed to use just it and
  replace instances of IWLCORE with it. The module name does not change
  and is still iwlcore.
- Both IWLAGN and IWL3945 are selecting FW_LOADER, we can thus just move
  this up to one select when IWLWIFI is selected.
- IWL5000 now supports Intel Wireless Wifi 100, 6000, and 6050 series.
- Now that 3945 depends on IWLWIFI we can also indicate its dependency on
  MAC80211_LEDS and LEDS_CLASS at this level.
- IWLAGN_LEDS is not used by driver - remove it.
- IWLAGN_SPECTRUM_MEASUREMENT actually depends on IWLWIFI as it forms part
  of iwlcore module. Move this config up in Kconfig to reflect that and also
  change name to IWLWIFI_SPECTRUM_MEASUREMENT.
- CONFIG_IWLWIFI_RFKILL is used by iwlagn as well as iwl3945, add text to
  description that indicates this.
- CONFIG_IWL3945_RFKILL does not exist - remove usage from driver.
- Add "iwlagn" to end of description of IWLAGN to help people understand
  what iwlagn means in rest of Kconfig text.
- Add "iwl3945" to end of description of IWL3945 to help people understand
  what iwlagn means in rest of Kconfig text.
- Change IWLWIFI_DEBUGFS description to indicate that only iwlagn supports
  it (for now).

Here we do two things:

First, revert "iwlwifi: save PCI state before suspend, restore after
resume".  That misguided patch led to being unable to use iwlwifi
devices after resume.

Next, indicate to PCI driver that the saved PCI state is valid during suspend.

We restore PCI state and enable the device when network interface is created,
similarly PCI state is saved and the device is disabled when network interface
is removed. Thus, when .suspend is called the PCI state is saved and device
is disabled. This is the case even if an interface is never created as PCI
state is saved and device disabled during .probe.

PCI driver assumes PCI state is saved in .suspend. Saving the state at this
time will save state of disabled device and thus cause problems during
resume (resuming a disabled device). We thus indicate directly to PCI
driver that current PCI saved state is valid.

The iwl_rxon_cmd is really just a iwl3945_rxon_cmd structure extension.
So, we can use the *_rxon fields from iwl_priv instead of the 3945 specific
ones (*39_rxon). We have to then be careful when submitting REPLY_RXON host
commands, since the command length as to be set according to the HW. As
another precaution the reserved4 and reserved5 fields are cleared before being
sent to the 3945.

With the *39_rxon removal, a lot of duplicated code can be removed from the
3945 code base.
