common/lcd_console: introduce display/framebuffer rotation

Browse source 
Sometimes, for example if the display is mounted in portrait mode or even if it
is mounted landscape but rotated by 180 degrees, we need to rotate our content
of the display respectively the framebuffer, so that user can read the messages
which are printed out.

For this we introduce the feature called "CONFIG_LCD_ROTATION", this may be
defined in the board-configuration if needed. After this the lcd_console will
be initialized with a given rotation from "vl_rot" out of "vidinfo_t" which is
provided by the board specific code.

If CONFIG_LCD_ROTATION is not defined, the console will be initialized with
0 degrees rotation.

CONFIG_LCD_ROTATION
Sometimes, for example if the display is mounted in portrait
mode or even if it's mounted landscape but rotated by 180degree,
we need to rotate our content of the display relative to the
framebuffer, so that user can read the messages which are
printed out.
Once CONFIG_LCD_ROTATION is defined, the lcd_console will be
initialized with a given rotation from "vl_rot" out of
"vidinfo_t" which is provided by the board specific code.
The value for vl_rot is coded as following (matching to
fbcon=rotate:<n> linux-kernel commandline):
0 = no rotation respectively 0 degree
1 = 90 degree rotation
2 = 180 degree rotation
3 = 270 degree rotation
If CONFIG_LCD_ROTATION is not defined, the console will be
initialized with 0degree rotation.
CONFIG_LCD_BMP_RLE8
Support drawing of RLE8-compressed bitmaps on the LCD.
