This makes the early printk support somewhat more flexible,
moving the port definition to a config option, and making the
port initialization configurable for sh-ipl+g users.
At the same time, this allows us to trivially wire up the
SH7780 SCIF0, so that's thrown in too more or less for free.

This enables support for 4K stacks on SH.
Currently this depends on DEBUG_KERNEL, but likely all boards
will switch to this as the default in the future.

This adds a DEBUG_STACK_USAGE and DEBUG_STACKOVERFLOW for SH.

We had our own version, which serves no purpose. Simply
hook SH in to the generic one.

Currently the CPU subtype options are cluttering up arch/sh/Kconfig somewhat.
Given that, this moves all of that in to its own arch/sh/mm/Kconfig. Things
like cache configuration are also moved to this new location.
This also adds support for strict CPU tuning on newer cores, which requires
the addition of as-option.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
