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,
};

Make 2 different folders for armv7 and aarch64 assembly neatlibc
functions. Add the neatlibc submodule, make it work against the
Makefile system. Pray.
