This changes the parameters for i8259_init so that it takes two
parameters: a physical address for generating an interrupt
acknowledge cycle, and an interrupt number offset. i8259_init
now sets the irq_desc[] for its interrupts; all the callers
were doing this, and that code is gone now. This also defines
a CONFIG_PPC_I8259 symbol to select i8259.o for inclusion, and
makes the platforms that need it select that symbol.

Now instead of having a ppc_md function, we just have a variable
which says whether to do the i8259 irq canonicalization or not,
and set that variable on the platforms that need that. It looks
to me that radstone_ppc7d was trying to use irq canonicalization
for something else in a broken kind of way - it will need to be
fixed properly.

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!
