SSD2119: backlight control

- Backlight uses PWM on TIM4 CH2.
- Updated readme.
- Updated gdisp_lld.c: moved from lld_gdisp_* to gdisp_lld_* functions
  names format.
- One forgotten GDISP_LLD() macro removal.
- General code cleanup (make diff with -w parameter ;))

-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_embest_dmstf4bb_fsmc.h or gdisp_lld_board_embest_dmstf4bb_fsmc.h file as a basis.

-		Currently known boards are:

-			BOARD_EMBEST_DMSTF4BB		- GPIO interface

-			BOARD_EMBEST_DMSTF4BB_FSMC	- FSMC interface

-

-	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

+Description:
+
+Driver for LCD with 16-bit interface in 8080 mode (65k colors).
+
+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_embest_dmstf4bb_fsmc.h or gdisp_lld_board_embest_dmstf4bb_fsmc.h file as a basis.
+		Currently known boards are:
+			BOARD_EMBEST_DMSTF4BB		- GPIO interface
+			BOARD_EMBEST_DMSTF4BB_FSMC	- FSMC interface
+		Both board configurations assume you have STM32_PWM_USE_TIM4 set to TRUE in your mcuconf.h.

+	d) The following are optional - define them if you are not using the defaults below:
+		#define GDISP_SCREEN_WIDTH	320
