Update the driver to support the device tree and the driver model.
Timings and panel parameters are now loaded from the device tree.
The DM code replaces the am335x_lcdpanel structure with
tilcdc_panel_info taken from the linux kernel, as well the management
of additional parameters not covered in the legacy code. In addition,
the am335x_lcdpanel structure contains parameters and operations that
were probably a requirement of the board for which this driver was
developed and which, however, were not developed in the linux kernel.
All this led to rewrite th DM controller initialization code, except
for the pixel clock setting that is executed in a function created in a
previous patch with code taken from the legacy am335xfb_init.
The patch has been tested on a custom board with u-boot 2018.11-rc2 and
the following device-tree configuration:
panel {
compatible = "ti,tilcdc,panel";
pinctrl-names = "default";
pinctrl-0 = <&lcd_enable_pins>;
enable-gpios = <&gpio0 31 0>;
backlight = <&backlight>;
status = "okay";
u-boot,dm-pre-reloc;
panel-info {
ac-bias = <255>;

};

Many boards do not use all selected framebuffer depth
configurations, for such boards there is some unused
code in video and console uclass routines. Make depth
specific code optional to avoid dead code and slightly
reduce binary size. Also make ANSI code optional for
the same reason. When i.e. using only VIDEO_BPP16 the
code size shrinks (below values when using gcc-7.3.0):
$ ./tools/buildman/buildman -b video-wip -sS wandboard

The STM32 LTDC display controller provides a parallel digital RGB and
signals for horizontal, vertical synchronization, Pixel Clock and Data
Enable as output to interface directly to a variety of LCD and TFT panels.
The LTDC main features are:
- 24-bit RGB Parallel Pixel Output, Programmable timings & polarity for
HSync, VSync and Data Enable.
- 2 layers with Blending, Color Keying, Window position & size,
Dithering, Background color, Color Look-Up Table (CLUT).
- Supported layer color formats: ARGB8888, RGB888, RGB565, ARGB1555,
ARGB4444, L8 CLUT, AL44 & AL88
This LTDC driver:
- supports: RGB parallel output with timings & polarity, 1 layer
in RGB565.
- supports but with hard-coded configurations: blending, window
position & size (crop), background color.
- does not support yet: rgb888, argb8888, 8-bit clut, dithering.

LTDC IP and has been tested on stm32 f746-disco board.
