iwmc3200wifi: remove driver for unavailable hardware 

This hardware never became available to normal humans.  Leaving this
driver imposes unwelcome maintenance costs for no clear benefit.

config IWM
tristate "Intel Wireless Multicomm 3200 WiFi driver (EXPERIMENTAL)"
depends on MMC && EXPERIMENTAL
depends on CFG80211
select FW_LOADER
select IWMC3200TOP
help
The Intel Wireless Multicomm 3200 hardware is a combo
card with GPS, Bluetooth, WiMax and 802.11 radios. It
runs over SDIO and is typically found on Moorestown
based platform. This driver takes care of the 802.11
part, which is a fullmac one.
If you choose to build it as a module, it'll be called
iwmc3200wifi.ko.
config IWM_DEBUG
bool "Enable full debugging output in iwmc3200wifi"
depends on IWM && DEBUG_FS
help
This option will enable debug tracing and setting for iwm
You can set the debug level and module through debugfs. By
default all modules are set to the IWL_DL_ERR level.
To see the list of debug modules and levels, see iwm/debug.h
For example, if you want the full MLME debug output:
echo 0xff > /sys/kernel/debug/iwm/phyN/debug/mlme
Or, if you want the full debug, for all modules:
echo 0xff > /sys/kernel/debug/iwm/phyN/debug/level
echo 0xff > /sys/kernel/debug/iwm/phyN/debug/modules
config IWM_TRACING
bool "Enable event tracing for iwmc3200wifi"
depends on IWM && EVENT_TRACING
help
Say Y here to trace all the commands and responses between
the driver and firmware (including TX/RX frames) with ftrace.

/*
* Hardware Abstraction Layer for iwm.
*
* This file mostly defines an abstraction API for
* sending various commands to the target.
*
* We have 2 types of commands: wifi and non-wifi ones.
*
* - wifi commands:
* They are used for sending LMAC and UMAC commands,
* and thus are the most commonly used ones.
* There are 2 different wifi command types, the regular
* one and the LMAC one. The former is used to send
* UMAC commands (see UMAC_CMD_OPCODE_* from umac.h)
* while the latter is used for sending commands to the
* LMAC. If you look at LMAC commands you'll se that they
* are actually regular iwlwifi target commands encapsulated
* into a special UMAC command called UMAC passthrough.
* This is due to the fact the host talks exclusively
* to the UMAC and so there needs to be a special UMAC
* command for talking to the LMAC.
* This is how a wifi command is laid out:
* ------------------------
* | iwm_udma_out_wifi_hdr |
* ------------------------
* | SW meta_data (32 bits) |
* ------------------------
* | iwm_dev_cmd_hdr |
* ------------------------
* | payload |
* | .... |
*
* - non-wifi, or general commands:
* Those commands are handled by the device's bootrom,
* and are typically sent when the UMAC and the LMAC
* are not yet available.
* * This is how a non-wifi command is laid out:
* ---------------------------
* | iwm_udma_out_nonwifi_hdr |
* ---------------------------
* | payload |
* | .... |
*
* All the commands start with a UDMA header, which is
* basically a 32 bits field. The 4 LSB there define
* an opcode that allows the target to differentiate
* between wifi (opcode is 0xf) and non-wifi commands
* (opcode is [0..0xe]).
*
* When a command (wifi or non-wifi) is supposed to receive
* an answer, we queue the command buffer. When we do receive
* a command response from the UMAC, we go through the list
* of pending command, and pass both the command and the answer
* to the rx handler. Each command is sent with a unique
* sequence id, and the answer is sent with the same one. This
* is how we're supposed to match an answer with its command.
* See rx.c:iwm_rx_handle_[non]wifi() and iwm_get_pending_[non]wifi()
* for the implementation details.
