9c7a41e8d3 Chisel3: bulk connect is not commutative 
We haven't decided if this is a FIRRTL limitation that we should relax,
or a backwards incompatibility we're forced to live with.  Should make
for lively debate.

0686bdbe28 Avoid cross-module references 
You can't instantiate a Vec in one module and use it in another.
An idiosyncrasy of the Chisel2 implementation let this one slip by.
In this case, it's just a matter of using def instead of val.

ea76800d1a Fix data array reset bug 
io.resp.valid could have been valid the cycle after reset, causing the
write mask in the acquire tracker to have an erroneous value after reset.
This caused the L1 I$ to be refilled with the wrong data.

This probably only affects programs loaded with +loadmem and so shouldn't
matter for the EOS24 silicon.  It should only affect the first L2 xact,
which, in practice, would be an HTIF write to load the program.
