[PATCH] sh: Drop hp690 discontig support
There was only one board using this (hp690 specifically), and it just so
happens that it's only physically discontiguous at the "normal" P1 offset. If
we bump up the P1 offset, it's possible to hit a shadowed region of memory
where we suddenly become magically contiguous.
As people have been using this shadowed region workaround for quite some time
(and without any adverse effects), it's time to drop the left over discontig
bits that no longer have any practical use (it was always very much
hp690-centric to begin with).
