iwmc3200wifi: Add new Intel Wireless Multicomm 802.11 driver

This driver supports Intel's full MAC wireless multicomm 802.11 hardware.
Although the hardware is a 802.11agn device, we currently only support
802.11ag, in managed and ad-hoc mode (no AP mode for now).

+/*
+ * 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 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 layed 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 layed 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.
