[kernel][vm] remove default KERNEL_ASPACE_BASE definition

Browse Source 
Require the platform or arch to provide it. The default was pretty
obsolete, assuming a 32bit arch with a split 50/50 mapping. May as well
make it a forced arch thing so that it's known to be correct.

Had to define it for OR1K, it was already defined for all the other
(known) architectures.
