WiFi and BT prevent going to deep sleep

rtcwake -d rtc0 -m mem -s 5

fails

Workaround :

before going to sleep unbind SDIO devices

modprobe -r mwifiex_sdio
modprobe -r btmrvl_sdio

Once the device wakes up, re-bind them:

modprobe mwifiex_sdio
modprobe btmrvl_sdio

LPM doesn't work

/sys/devices/platform/imx93-lpm/mode
