Bluetooth: Add HCIUARTSETFLAGS and HCIUARTGETFLAGS ioctls
This patch introduces two new ioctls: HCIUARTSETFLAGS and HCIUARTGETFLAGS. The only flag available for now is HCI_UART_RAW_DEVICE which allows to initialize a UART device into RAW mode from userspace. This is particularly useful for experimenting with Bluetooth controllers that don't yet have proper support in BlueZ.
