ec1f901a38 tilelink2: move error from type into Bundle and add HintAck
We need Grant with errors too.
We also want to match response type to request type more easily.

63679bb019 Add support for L1 data scratchpads instead of caches
They fit in the same part of the address space as DRAM would be, and
are coherent (because they are not cacheable).

They are currently limited to single cores without DRAM.  We intend
to lift both restrictions, probably when we add support for
heterogeneous tiles.

dc9ae19936 Work-around for current Scala compiler "structural type loses implicits".
Running rocket-chip through the chisel3 gsdt branch which supports stricter connection checks and uses implicit definitions to deal with "old" direction overrides, exposed a possible bug in the Scala compiler.

    [error] .../src/main/scala/uncore/devices/Prci.scala:27: value asOutput is not a member of uncore.devices.PRCIInterrupts{val mtip: chisel3.core.Bool; val msip: chisel3.core.Bool}
    [error] possible cause: maybe a semicolon is missing before `value asOutput'?
    [error]   }.asOutput
    [error]     ^
    [error] one error found
    [error] (uncore/compile:compileIncremental) Compilation failed

This change isn't strictly required for current chisel3 code, but is being submitted in anticipation of an eventual merge of the gsdt branch prior to a compiler fix.
