Currently we are checking if the function returns nonzero. This is fine,
however it adds a lot of bloat, for example the late_init initcall is
practically never used and is only a stub function that returns zero. So
- add a proper initcall macro to prepare for cleaning up unused stubs.

As we can make use of the video_info struct for base address,
this argument is not required anymore and only breaks havoc on
boards that don't set the CONFIG option.
Jokes aside, commit adds support for colored indexes based on the
loglevel, introduces a better simplefb probing that does not depend
on hardcoded config options. Implementing support for fdt should be
easier now.
Since we don't have to worry about writing positionally-independent
code, we can safely pass around globally defined structures and
have more fun with pointers without falling into UB.
With support for this board also come the following changes:
- rework blobs handling to get past the 0 size bug
- basic cpu "set up" in start.S
- assembly memcpy
- uart debugging
Implement an ACPM driver with helpers to allow communicating
with PMIC via SPMI for newer exynos devices.

Speedy is a serial communication bus that is typically used in
Exynos SoC devices for communicating with a PMIC. Implement
basic support for it, as well as add its first user - s2mps17 in
board-dreamlte.
Also, while at it, implement a simple readl function.

This actually breaks the armv7 port. It has to be revisited in the
future, since it not only is not compilable right now, but also
cannot boot linux properly. TODO
Also introduce a new C-based __memcpy_optimized that does not
cause an exception on some devices when copying the initramfs.
This issue has to be debugged further.

Implement 8 loglevels to use with printk:
While at it, separate the font in a new "video" directory, which
also makes space for a proper video probing implementation. Fill
in the font from 32 to 256. Scale the font to render twice as big.
Implement dynamic line length detection. Change a few things here
and there to follow the linux kernel code style. Add a nice logo.

This is meant to replace the current Kconfig / SoC / Board files
configuration, which is ugly and annoying to maintain. Begin
by creating the board files registration framework and
transitioning all exynos boards to it. This also opens room for
creating the drivers registration framework in the future.
All non-samsung boards will be no longer able to do their board
configuration until they're also transitioned.
Every new board must have the following structure:
struct board_data default_board = {
.name = "DEFAULT",
.init = NULL,
.late_init = NULL,
.driver_setup = NULL,
};
