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.

Move onto using asmdefs macros in assembly files. Implement an
assembly-based memcpy for aarch64 and a C-optimized memset, while
also making place for replacing functions with more optimized ones
in the future.

unic is a small library of C functions that is currently written
in plain C. It's purpose isn't to be fast, but "universal" - as
in include as little architecture-specific code as possible.
The old neatlibc still resides, but isn't being built. There is
still more to do, including implementation of memory management,
so keep it there for now.
