The non-module SMM programs were not being garbage collected
during linking. Do this so that one doesn't have to add dependencies
for unused functions in SMM.
TEST=Interrogated readelf -e smm.elf on both builds as well as diffed
the symbol table. Runtime testing was not done.

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cannot go missing or out of date.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).
BUG=None
TEST=Booted normally and in recovery mode, checked suspend/resume and
the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and
Pit. Compiled Ryu, Storm and Urara, manually compared the disassemblies
with ToT and looked for red flags.

Commit f69a99db (coreboot: x86: enable gc-sections) added
gc-sections to the linker command line. The SMM-specific
linker scripts were not interrogated to see if all the
sections were being included properly. .data, .bss, and .sbss
did not have the proper globs set to put the SMM programs in
the expected order.
Lastly, explicitly set the ENTRY for the SMM programs.

We don't need exception handlers and they waste space.

while others dislike them being extra commits, let's clean them up once and
for all for the existing code. If it's ugly, let it only be ugly once :-)

parts.
This should help to reduce the code duplication for Rudolf's K8/VIA SMM
implementation...
