 MT7663U and MT7668U UART devices

Hi Sean,

> bluetooth is a built-in device on MediaTek SoC communicating with the host
> through BTIF serial transport. Thus, extra setup sequence is necessary
> for these standalone devices such as remote regulator and reset control via
> GPIO, baud rate changing handshake between the host and device and so on.
