rocketchip: move memory channel Xbar from coreplex to rocketchip
...
We want to keep the banks split in the outer SoC if there is an L3.
Furthermore, each channel might go to different memory subsystems,
like DDR/HMC/Zero, from rocketchip.

Configs: use a uniform syntax without Match exceptions ( #507 )
...
* Configs: use a uniform syntax without Match exceptions
The old style of specifying Configs used total functions. The only way to
indicate that a key was not matched was to throw an exception. Not only was
this a performance concern, but it also caused confusing error messages
whenever you had a match failure from a lookup within a lookup. The
exception could get handled by an outer-lookup that then reported the wrong
key as missing.
