Mateusz Zalega 2d281b3252 arm: goni: dfu: Add support for DFU to Goni target
Proper adjustment for supporting DFU at GONI target has been made.
The s5p_goni.h file has been updated. Moreover the code for low level
USB initialization has been added to GONI board code.

The malloc pool has been enlarged in order to support larger buffer
sizes needed by DFU implementation.
