Started SSD2119 driver based on ili9328 driver....

Started SSD2119 driver based on ili9328 driver. -IF more or less functionnal /!\ need to check FSMC config -Need to check mid point circle algo -need to generate good fonts! -Should merge ili and ssd driver in one since the interface is the same, we can detect the chip with Device Code. Added Stm32Discovery extension board bsp.
