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.
