This series is part of my ongoing efforts to cleanup common/lcd code (and at
some point merge it with the CONFIG_VIDEO code).
This series focuses on eliminating platform specific #defines from lcd.c code,
and then adds a few platform independent code refactors and cleanups on top of
that. A small note on the series:
- The patch "lcd: split configuration_get_cmap" turned out to be a little
problematic: the goal was to move all platform specific code to the appropriate
lcd/fb drivers, and keep the generic case in lcd.c as a weak function.
This was not possible to do for configuration_get_cmap(), because the weak
version still has to compile even if it is overridden, and unfortunately the
generic case references panel_info, which is a struct that varies depending on
the configuration, and does not always have a cmap field. This demonstrated that
the visibility of panel_info should be reviewed, and that there might be a need
for some kind of lcd_generic driver.
Since this may warrant a series of its own, I opted to tentatively implement
the generic configuration_get_cmap() function in lcd.h as static function, and
plan to revisit it in the next series.
The end result was compile tested on arm and powerpc, and tested on cm_t35
(splash screen feature). Rebased on current mainline.
Changes in V2:
- Minor commit message changes (such as s/platform specific/platform-specific/,
s/Raspberry Pi config file is updated to compile the new file/Raspberry Pi is updated to accommodate the changes/)
- patch 2: define configuration_get_cmap() prototype only once.

common/lcd code is full of platform-specific code and definitions, which
ideally should reside with the respective driver code. Take a step towards that
goal by moving platform-specific structs from lcd.h to their own header files.
The structs for the generic case (the #else for all the platform-specific
cases) is retained in lcd.h as the default case.

configuration_get_cmap() is multiple platform-specific functions stuffed into
one function. Split it into multiple versions, and move each version to the
appropriate driver to reduce the #ifdef complexity.

Reduce the amount of platform-specific code in common/lcd.c by moving Atmel
implementation of fb_put_word() to atmel_lcdfb.c. Since we must also have a
default implementation for everybody else, make the remainder of the code
into a weak function.

Reduce the bitmap_plot #ifdef complexity by extracting Atmel-specific code for
setting cmap into a new function lcd_logo_set_cmap(), which is implemented in
atmel_lcdfb driver and defined as part of common/lcd.c api with a weak dummy
version. In the Atmel implementation, ARRAY_SIZE(bmp_logo_palette) is
switched for BMP_LOGO_COLORS to avoid having to include bmp_logo_data.h, which
would cause a compilation error because the logo data and palette arrays would
be defined twice.
This is a step towards cleaning bitmap_plot() of platform-specific code.

The name "bitmap_plot" is misleading because it implies that this is a generic
function capable of dealing with any bitmap, but its implementation only works
with the logo data.
Rename the function to better reflect this.

We now have api functions that can support compiling simplefb code as its own
module. Since this code is not part of the display functionality, extract it
to its own file.
Raspberry Pi is updated to accommodate the changes.

lcd_logo() currently performs tasks well beyond just displaying the logo.
It has code which displays splash image, it has logic which determines
when the different display features are displayed, and it is coupled with
the lcd console because it holds the responsibility of returning the
lcd console base address.
Make lcd_logo() just about the logo by:
* Moving splash image display code into a dedicated function
* Moving the logic regarding when various features are displayed to
lcd_clear() (which is arguably not the correct name for housing such
code either, but it is currently the most fitting location code wise)
* Move the responsibility of setting the console base address to
lcd_clear() too.

Here, I think no need to do the CONFIG_LCD_LOGO check, return
bmp_logo_palette directly, as it will be used when use bmp command in 8
bit mode. However, no hardware to test LCDC work or not in 8 bit mode :(

This would make CONFIG_LCD_LOGO a prerequisite for this driver (bmp_logo_palette does not exist otherwise), and I don't think it's right to couple the two.
