This patch does some general cleanup in the Rockchip clock code, and
adds some more assertions regarding the PLL VCO and output frequency
ranges. It changes all PLL divisors to use the lowest values that can
still hit the target frequency, since higher NR values lead to higher
jitter and higher NO values increase power draw.
Also change DDR3 frequency code to hardcode the optimal divisors for
certail frequencies. As a little hack we will interpret 666000000 to
actually mean 666666666.6P (and analogous for 533MHz), since that's what

Turns out making the compilation of every single source file depend on
the auto-generated build.h in CL:219170 wasn't really such a great idea
for incremental builds. Who would've thought.
However, it's still undesirable that individual Makefiles for sources
that actually include build.h need to add that dependency manually.
Therefore, this patch fixes the issue by using $(generic-deps) as an
order-only prerequisites in rules. This kind of prerequisite is still
made before the target if it doesn't exist, but it is not automatically
updated based on the timestamp. Also removed some additional manual
build.h dependencies that I must somehow overlooked in the old patch.
The files that actually include build.h still get it as a normal
prerequisite through the automatic dependency rule in <filename>.d that
is created by GCC's -MMD option. $(generic-deps) only solves the
chicken-and-egg problem of where build.h comes from in fresh/cleaned
build directories that don't have any .d dependency files yet.

This patch creates a new mechanism to define the static memory layout
(primarily in SRAM) for a given board, superseding the brittle mass of
Kconfigs that we were using before. The core part is a memlayout.ld file
in the mainboard directory (although boards are expected to just include
the SoC default in most cases), which is the primary linker script for
all stages (though not rmodules for now). It uses preprocessor macros
from <memlayout.h> to form a different valid linker script for all
stages while looking like a declarative, boilerplate-free map of memory
addresses to the programmer. Linker asserts will automatically guarantee
that the defined regions cannot overlap. Stages are defined with a
maximum size that will be enforced by the linker. The file serves to
both define and document the memory layout, so that the documentation
cannot go missing or out of date.
The mechanism is implemented for all boards in the ARM, ARM64 and MIPS
architectures, and should be extended onto all systems using SRAM in the
future. The CAR/XIP environment on x86 has very different requirements
and the layout is generally not as static, so it will stay like it is
and be unaffected by this patch (save for aligning some symbol names for
consistency and sharing the new common ramstage linker script include).
