wl12xx: Modify memory configuration for 128x/AP

The 128x/AP firmware does not yet support dynamic memory. Temporarily,
the memory configuration for the 127x was used both for 127x/AP as well
as 128x/AP. Since the two chips don't have the same number of memory
blocks, TP was significantly degraded.

This hasn't been fine tuned yet, but using the base 128x numbers
(without dynamic memory) seems to yield much better results (around 30%
more). Additional fine tuning will be required in the future.
