Add functions to configure and query the WiFi interference mitigation
mode:

  • cyw43_ll_wifi_set_interference_mode / cyw43_wifi_set_interference_mode
  • cyw43_ll_wifi_get_interference_mode / cyw43_wifi_get_interference_mode

The mode is controlled via the WLC_SET/GET_INTERFERENCE_MODE ioctls and
accepts one of the CYW43_IFMODE_ constants:

CYW43_IFMODE_NONE (0) - disabled
CYW43_IFMODE_NONWLAN (1) - non-WLAN interference mitigation
CYW43_IFMODE_WLANMANUAL (2) - adjacent channel interference (ACI)
CYW43_IFMODE_AUTO (3) - automatic ACI
CYW43_IFMODE_AUTONOISE (4) - automatic ACI with noise reduction

Unlike the roam APIs, interference mode applies globally to the radio
and is not gated on STA_IS_ACTIVE as it affects both STA and AP
interfaces in apsta mode.
