Simplify TileLink Narrower
...
It's not necessary to use addr_beat to determine where to put the Grant
data. Just stripe it across all lanes.
This also gets rid of a dependence on addr_beat in Grant. If we move
towards a regime where TileLink is only narrowed, not widened, we may
be able to drop the field altogether.

Fix narrow read/write behavior for AXI converters and fix L2 bugs
...
Until recently, we were assuming that the data channel in AXI was always
right-justified. However, for narrow writes, the data must actually be
aligned within the byte lanes. This commit changes some of the
converters in order to fix this issue.
There was a bug in the L2 cache in which a merged get request was
causing the tracker to read the old data from the data array,
overwriting the updated data acquired from outer memory. Changed it so
that pending_reads is no longer set if the data in the buffer is already
valid.
There was a bug in the PortedTileLinkCrossbar. The new GrantFromSrc and
FinishToDst types used client_id for routing to managers. This caused
bits to get cut off, which meant the Finish messages could not be routed
correctly. Changed to use manager_id instead.

Add tracegen scripts inc. bugfix from @mwachs5
...
A step towards moving the tracegen scripts from rocket-chip to
groundtest. I will raise an issue requesting that the scripts are now
removed from rocket-chip by someone with write access.
I have updated the README to account for the move.
This commit includes a bugfix from @mwachs5 (with slight mods by me)
relating to potential division by zero in toaxe.py.
