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.
