arm: Put exception_stack into BSS
"Hey guys, I have this awesome idea! How about we put a huge array
filled with 0xa5 into the data segment of our uncompressed romstage
for no particular reason? Give our SPI driver something to do so it
doesn't get too bored, you know?"
Guess it pays off to just hexdump our image and sanity-check it top to
bottom every once in a while...
Also reduces the size because 8K is crazy just to print a bunch of
registers (256 bytes ought to be enough for anybody).

arm: Remove exception_test()
The exception_test() mechanism might have been useful when exceptions
were first implemented, but now that they are pretty stable it's really
not necessary anymore (especially not on every single boot in production
Chromebooks). It forces a simple unaligned access, and as we start
having exceptions in stages that might not have paging turned on yet,
it's better to remove that completely.
Also removed the duplicated implementations of SCTLR-stuff and switched
to the existing ones in cache.h.
