Move bt coex functions to iwl-agn-lib.c, so those functions
can be shared by multiple wifi/bt combo devices

- * Macros to access the lookup table.
- *
- * The lookup table has 7 inputs: bt3_prio, bt3_txrx, bt_rf_act, wifi_req,
- * wifi_prio, wifi_txrx and wifi_sh_ant_req.
- *
- * It has three outputs: WLAN_ACTIVE, WLAN_KILL and ANT_SWITCH
- *
- * The format is that "registers" 8 through 11 contain the WLAN_ACTIVE bits
- * one after another in 32-bit registers, and "registers" 0 through 7 contain
- * the WLAN_KILL and ANT_SWITCH bits interleaved (in that order).
- *
- * These macros encode that format.
