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.
