fix macro anno error

[donggyukim]

I just fixed an error, not a warning. We should use new annotation APIs in the end.

@edwardcwang Also barstools should be bumped in hammer?

[edwardcwang]

Seems fine overall, though I have 2 concerns for which it'd be good for us to talk about:

1. Are we committed to relying on firrtl 1.2 (master) now, or do we want to rely on release versions of firrtl (currently 1.1)? I'm fine with us switching to firrtl 1.2 - would just be good to be explicit about that.

macros/src/main/scala/MacroCompiler.scala:720: type mismatch;
[error]  found   : Seq[firrtl.annotations.Annotation]
[error]  required: Option[firrtl.AnnotationMap]
[error]         val state = CircuitState(circuit, HighForm, annotations)
[error]                                                     ^
[error] one error found
[error] (macros/compile:compileIncremental) Compilation failed

2. Seem like firrtl 1.2 (master) introduces stricter checks, whereas the same code passes with firrtl 1.1:

[edwardcwang]

As for hammer, yes, we should bump barstools at some point.

[donggyukim]

For 1, I think we should wait until firrtl 1.2 is released.

For 2, I don't see those issues with rocketchip master. How can I reproduce it?

[edwardcwang]

The error is reproducible by running sbt "project macros; test" with this commit + firrtl 1.2, I think.

[donggyukim]

We should update the firrtl files in the test later.
