ARM: dts: stm32: Enable Bluetooth on AV96 



The WiFi/Bluetooth chip is attached to USART2 on AV96 as well, describe
it in DT to make it available. Remove BT LED and turn it into a shutdown
GPIO, because the GPIO line controls the BT_REG_ON signal. The LED is just
an indicator connected to the same line, but not the primary function.
