56867c3bc6 Fix double debug message output on serial port
SBL allows debug message to be redirected to output console besides
the serial port. However, serial port itself could be part of the
output console device as well. In this case the debug message will
be printed twice. This patch added check to this condition and skip
the redundant print.

It fixed #349.

2255bc10b0 Enable basic framebuffer text console output
This patch simplifies the GraphicsLib code and adds an abstraction layer
for printing to a virtual "console," through the familier
ConsoleWrite(buffer, len) style function call.

ConsoleWrite can be configured to output to either the serial port, or
the display framebuffer, or both. This primarily enables the command
shell to be used with a display and keyboard.
