This patch adds a simple HCI UART (H4) driver that currently maps to the second UART in the system. The main intention is to use this together with qemu for accessing the Bluetooth controller available on the host OS side. The H4 HCI transport protocol is perhaps the simplest of the standard HCI transports. It consists of a single byte in the beginning of each packet which indicates the type of the packet: HCI event, HCI command, ACL data, or SCO data (which we don't use at the moment).
