Wey-Yi Guy be663ab670 iwlwifi: split the drivers for agn and legacy devices 3945/4965 
Intel WiFi devices 3945 and 4965 now have their own driver in the folder

	drivers/net/wireless/iwlegacy

Add support to build these drivers independently of the driver for
AGN devices. Selecting the 3945 builds iwl3945.ko and iwl_legacy.ko,
and selecting the 4965 builds iwl4965.ko and iwl_legacy.ko. iwl-legacy.ko
contains code shared between both devices.

The 3945 is an ABG/BG device, with no support for 802.11n. The 4965 is a 2x3
ABGN device.

* @fw_name_pre: Firmware filename prefix. The api version and extension
* (.ucode) will be added to filename before loading from disk. The
* filename is constructed as fw_name_pre<api>.ucode.
* @ucode_api_max: Highest version of uCode API supported by driver.
* @ucode_api_min: Lowest version of uCode API supported by driver.
* @scan_antennas: available antenna for scan operation
* @led_mode: 0=blinking, 1=On(RF On)/Off(RF Off)
*
* We enable the driver to be backward compatible wrt API version. The
* driver specifies which APIs it supports (with @ucode_api_max being the
* highest and @ucode_api_min the lowest). Firmware will only be loaded if
* it has a supported API version. The firmware's API version will be
* stored in @iwl_priv, enabling the driver to make runtime changes based
* on firmware version used.
*
* For example,
* if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
* Driver interacts with Firmware API version >= 2.
* } else {
* Driver interacts with Firmware API version 1.
* }
*
* The ideal usage of this infrastructure is to treat a new ucode API
* release as a new hardware revision. That is, through utilizing the
* iwl_hcmd_utils_ops etc. we accommodate different command structures
* and flows between hardware versions as well as their API
* versions.
