Benjamin Herrenschmidt 1441b2a859 litedram: l2: Latency improvements
This implements in the L2 cache the feature already in the L1s
allowing a request to be completed before the end of a refill
using partial line valid bits, and starting a refill from the
row of the first miss on that line instead of the beginning of
the line.

Benjamin Herrenschmidt 6828e93113 litedram: Test bench
The test bench test simple access forms for now, it's a starting point
but it already helped find/fix a bug.

Includes a litedram update to be able to operate the sim model without
inits.
