ARM: dts: stm32: Enable WiFi on AV96

Browse Source 
The WiFi/Bluetooth SDIO chip is attached to SDMMC3 on AV96, describe it
in DT to make it available. Remove WiFi LED and turn it into a regulator,
because it is a GPIO controlling the WL_REG_ON input of the WiFi chip.
The LED is just an indicator connected to the same line, but not the
primary function.
