> SecBoardInitLib is called to enable serial port before SerialPortInitialize and
> DEBUG().

> This is strongly assumed to be necessary for I2cHdmiDebugSerialPortLib in
> SEC phase, which presently initialises this way.
> 
> No testing was performed before, it's assumed too risky unless the GPIO
> happens to have the desired default. Presently, DEBUG() works in SEC
