Blackfin: drop 4KB reserve at end of memory
The point of this small chunk was to avoid anomaly 05000310. This never
really seemed to do what it was intended though -- no valid CPLBs exist
over the reserved memory, and there is often memory before it anyways (due
to the uClinux MTD and/or reserved DMA region). Plus, it doesn't address
the L1 instruction case.
So drop this chunk as it wastes memory and is affront to humanity.
