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.

but it already helped find/fix a bug.

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