initial commit: copy sources from SSD1289 

I started project of new driver: SSD2119. This work is based on SSD1289.
I don't know exactly if this one is the most similar to my one. It's
just an experiment. There is no accompanying board file of any flavor,
but the hardware lying on my desk is Embest DM-STF4BB with DM-LCD35RT
LCD module.

Changes already made:
- Copied entire drivers/gdisp/SSD1289 directory into
  drivers/gdisp/SSD2119.
- Changed every occurrence of "SSD1289" to "SSD2119" in each source
  file.

All the below routines are optional.
Defining them will increase speed but everything
will work if they are not defined.
If you are not using a routine - turn it off using
the appropriate GDISP_HARDWARE_XXXX macro.
Don't bother coding for obvious similar routines if
there is no performance penalty as the emulation software
makes a good job of using similar routines.
eg. If gfillarea() is defined there is little
point in defining clear() unless the
performance bonus is significant.
For good performance it is suggested to implement
fillarea() and blitarea().

To use this driver:
1. Add in your halconf.h:
a) #define GFX_USE_GDISP TRUE
b) Any optional high level driver defines (see gdisp.h) eg: GDISP_NEED_MULTITHREAD
c) If you are not using a known board then create a gdisp_lld_board.h file
and ensure it is on your include path.
Use the gdisp_lld_board_example.h or gdisp_lld_board_fsmc.h file as a basis.
Currently known boards are:
BOARD_FIREBULL_STM32_F103 - GPIO interface: requires GDISP_CMD_PORT and GDISP_DATA_PORT to be defined
d) The following are optional - define them if you are not using the defaults below:
#define GDISP_SCREEN_WIDTH 320
#define GDISP_SCREEN_HEIGHT 240
2. To your makefile add the following lines:
include $(GFXLIB)/drivers/gdisp/SSD2119/gdisp_lld.mk
