Commit 54229a7 (arm: Fix checkstack() to use correct stack size) didn't
quite hit the mark. Due to the crazy way our Kconfig includes work, It
accidentally set CONFIG_STACK_SIZE to 0 even on architectures that need
it.
This patch fixes the issue by moving everything back to a single entry
in src/Kconfig, making sure we end up with the intended numbers on all
architectures.
BRANCH=None
BUG=chrome-os-partner:34750
TEST=Built for Pinky, Urara, Falco and Ryu. Confirmed that the generated
.config contained CONFIG_STACK_SIZE=0x0 for the former two, and
CONFIG_STACK_SIZE=0x1000 for the latter.

checkstack() runs at the end of ramstage to warn about stack overflows,
and it assumes that CONFIG_STACK_SIZE is always the size of the stack to
check. This is only true for systems that bring up multiprocessing in
ramstage and assign a separate stack for each core, like x86 and ARM64.
Other architectures like ARM and MIPS (for now) don't touch secondary
CPUs at all and currently don't look like they'll ever need to, so they
generally stay on the same (SRAM-based) stack they have been on since
their bootblock.
This patch tries to model that difference by making these architectures
explicitly set CONFIG_STACK_SIZE to zero, and using that as a cue to
assume the whole (_estack - _stack) area in checkstack() instead. Also
adds a BUG() to the stack overflow check, since that is currently just
as non-fatal as the BIOS_ERR message (despite the incorrect "SYSTEM
HALTED" output) but a little more easy to spot. Such a serious failure
should not drown out in all the normal random pieces of lower case boot
spam (also, I was intending to eventually have a look at assert() and
BUG() to hopefully make them a little more useful/noticeable if I ever
find the time for it).
BRANCH=None
BUG=None
TEST=Booted Pinky, noticed it no longer complains about stack overflows.
Built Falco, Ryu and Urara.

With kconfig understanding wildcards, we don't need
Kconfig files that just include other Kconfig files
anymore.

Add the build infrastructure and basic architectural support required
to build for targets using the MIPS architecture. This is sufficient
to run on a simulator, but will require the addition of some cache
maintenance and timer setup in order to run on real hardware.
