Support EPDC.
E-Ink feature is supported by i.MX6DL/SL/SLL/ULL and i.MX7D.This driver supports user defined logo file, if there is no logo file, it will
draw a black border around a white screen.If need to enable EPDC, a waveform file is required to let all
work.Since we need LCD_MONOCHROME mode for EPDC, we introduce LCD_MONOCHROME
support.Please refer to Linux Reference Manual for how to flash WAVEFORM file.

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.Signed-off-by: Hannes Petermaier

[agust: fixed 'struct vidinfo' has no member named 'vl_rot' errors]

For coming implementation of lcd_console rotation, we will need some more
variables for holding information about framebuffer size, rotation, ...For better readability we catch all them into a common structure.

Don't call the lcd_getfgcolor and lcd_getbgcolor within the "draw-loop", this
only wastes time.Signed-off-by: Hannes Petermaier

the capability of drawing some *str with count from lcd_drawchars is unnary.
It is always called from lcd_putc_xy with one character of and count = 1.So we simply rename lcd_drawchars into lcd_putc_xy and remove the loops inside.

Sometimes we do not want redirect u-boot's console to screen but anyway we want
write out some status information out of a u-boot script to the display.So we cannot use the normal "echo ....", instead we write explicitly using
"lcdputs ..." for writing to the actual cursor position on LCD.Signed-off-by: Hannes Petermaier

Sometimes we do not want redirect u-boot's console to screen but anyway we want
write out some status information out of a u-boot script to the display.To define the specific position of the string to be written, we have to set
the cursor with "setcurs" before writing.Signed-off-by: Hannes Petermaier

common/lcd.c is a mix of code portions that do different but related
things. To improve modularity, the various code portions should be split
into their own modules. Separate lcd console code into its own file.Signed-off-by: Nikita Kiryanov
