disable PHY and RF when stop WiFi and disable BT 1. Add disable PHY and RF when WiFi and BT are both disabled(including call sniffer disable API). 2. Do not init PHY and RF when cpu start. Init PHY and RF when call Wifi or BT start APIs(including sniffer enable API). 3. Add a temporary lib: librtc_clk.a and will delete it when CPU frequency switching function is done. 4. Add an function to get OS tick rate. 5. Do not put the whole pp.a in iram0, only put lmac.o, ieee80211_misc.o, ets_time.o and wdev.o in iram0. 2017-02-16 19:05:07 +08:00			`LIBS := core rtc rtc_clk`

Build: Handle WiFi & BT enabled/disabled combos gracefully as possible If using WIFI_INIT_CONFIG_DEFAULT, error message will point out lack of WiFi. Otherwise linker errors on WiFi symbols should help give a clue as to what is broken. Piggy-backs on changes in !420, ref github #230 #237 2017-01-16 11:52:15 +11:00			`endif`
