If the memory layout pushes the stack out of the default DCPLB coverage,
the exception handler may trigger a double fault by trying to push onto
the uncovered stack. So handle the exception stack similar to the kernel
by using the top of the scratch pad SRAM.

The default console size indirectly applies to length of env vars, so a
smaller length makes it hard to pass longer command lines to kernels.

The Blackfin port was using asm/blackfin-config-{pre,post}.h to setup
common Blackfin board defines. The common method now is to use config.h,
so convert blackfin-config-post.h to that. Rename the still Blackfin
specific blackfin-config-pre.h to config-pre.h so the naming conventions
at least line up.

We have common defines that we duplicate in various ways. Having an
arch specific config.h gives us a common location for those defines.
Eventually we should be able to replace this when we have proper
Kconfig support.
