Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

Font capabilities currently indicate whether font data is packed
horizontally or vertically, and this is used to control frame buffer
updates. The font bit ordering should likewise be recorded in the font
description, and any reversal to match the display applied when text is
being set in the frame buffer.

The specified order of fields wastes space when the cfb_font_caps enum
isn't packed. Reorder to avoid this behavior.
Also remove the unnecessary array size on the extern symbol declaration,
lest the compiler misinterpret the properties as being zero-length
arrays rather than pointers. (The idiom is already technically
using undefined behavior since we're relying on the linker rather than
the language to produce an array from the individual declarations.)

This macro provides the required alignment directives to ensure that the
font definitions are placed properly for iteration as members of an
array object.

move display.h to drivers/display.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

As mentioned in issue #12265, this API wasn't included in the generated
API docs because a doxygengroup directive was missing.

Add monochrome character framebuffer for monochrome
graphic dot matrix displays and electrophoretic displays.
These displays are mostly monochrome and can only display
black and some other color, for example white. Typically,
a byte controls 8 pixels, arranged vertically or horizontally
depending on the controller or settings.
The API is not suitable to display graphics, the purpose is
to display text or symbols. It is possible to use several fonts.
A font can also consist of graphic symbols only and thus,
for example, enable the realization of a menu.
