MFC r258779,r258780,r258787,r258822:

Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit. Instead use (1U << 31) which gets the
expected result.

Similar to the (1 << 31) case it is not defined to do (2 << 30).

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

Add in some definitions required for later iwn(4) device support.

This also clarifies a few existing fields.

Tested:

* Intel 5100

Submitted by: Cedric GROSS <cg@gross.info>

Break out the iwn(4) device IDs into if_iwn_devid.h, as well as add
IDs for new devices.

* Add new device IDs
* Extend the ID probe code to include the newer range of bits used
by later model devices

Tested:

* Intel 5100, STA mode

TODO:

* Test on Intel 4965, just to be sure

Submitted by: Cedric GROSS <cg@gross.info>

iwn(4) debugging improvements.

* Add in some new register debugging under IWN_DEBUG_REGISTER
* Make IWN_DEBUG an option now for building. I'll chase this up
with a commit to 'options' soon.

The DC calibration result obtained during initialization can't be
passed over to the runtime firmware on 6050 devices. Instead let
the runtime firmware do the calibration itself. This fixes support
for the 6050 series devices.

Notify firmware about various HT parameters once associated.

Add support for TX packet aggregation.

Add support for transmitting frames at MCS rates.

Prepare for transmitting frames at MCS rates:
- instead of calling iwn_plcp_signal() for every frame, map the expected
value directly within wn->ridx
- concat plcp, rflags and xrflags, there is no clean byte boundary within
the flags, for example the antenna setting uses bit 6, 7 and 8
- there is still need for a custom rate to plcp mapping, as those expected
by the hardware are not conform to the std

Use the enhanced TX power information availabe on newer EEPROMs.

The 6000 series adapters have a slightly different offset for band 6,
2GHz HT40 channels.

Add basic support for advanced bluetooth coexistence required
for 6005 gen2b (1030/6030) adapters.

Pull some features out of the firmware:
- If a ENH_SENS TLV section exit the firmware is capable of doing
enhanced sensitivity calibration.
- Newer devices/firmwares have more calibration commands therefore
hardcoding the noise gain/reset commands no longer works. It is
supposed to use the next index after the newest calibration type
support. Read the command index of the TLV section if available.

Add some new features:
- 6000 series devices need enhanced sensitivity calibration.
- 6000 series devices need a different setting for the shadow reg.
- set the IWN_FLAG_HAS_11N bit if the EEPROM says the device has 11n
support.

Just a whitespace sync, some more style(9) conform then others.

Instead of hardcoding TX rates and using that to fill the retry table
use the neogotiated ni_rates instead.

The 6005 series devices need additional temperature offset calibration
as well as the IWN_GP_DRIVER_CALIB_VER6 bit set.

Don't timeout when stopping DMA channels.

Remove IWN_FLAG_HAS_5GHZ and IWN_PCI_BAR0, both unused.

Add support for firmware images in "type-length-value" format.

- Add new IDs for 6000 series devices.
- The 6000 series WiMAX devices need a separate firmware.
- The b-gen devices are not hooked because the hardware revision type
is not know.

* Rename bluetooth coexistence flags, no binary change.
* Enable DC calibration and crystal calibration on Centrino Advanced-N
6250 parts.
* Workaround for a HW bug (does not affect 4965AGN) that may sporadically
affect latency under some rare circumstances. From a similar commit to
iwlwifi.
* Update sensitivity settings for 5000 series to workaround a performance
bug in the DSP (1000 is not affected so we keep the old values for 5000).
* Update sensitivity settings for 6000 series.
* Set differential gains on 6250 too (but use a 1.0 factor, not 1.5).
* Init OFDM sensitivity with min value (which depends on the chip)
instead of hardcoding it to 90.
* Read calibration version from ROM and set IWN_GP_DRIVER_CALIB_VER6
bit on 6x50 if version >= 6.
