ba478f2de5 mini.hv.dcp: Decode common messages
This accounts for most of the DCP traffic once macOS is booted. I used
a sophisticated side-channel hypervisor timing attack to determine the
message functions [ adding time.sleep(1) ]

6adf0c692c mini.trace.asc: Don't log handled messages
ASC handlers now return a boolean to indicate whether they successfully
handled the message (True if so). In that case, printing the underlying
mailbox traffic is redundant, so let's hide it.

98076ef693 usb: disable tps6598x interrupts
Restore the interrupt masks on chainload or HV guest start. The
interrupt mask is not restored on the USB-C port used by the hypervisor.
This prevents an interrupt storm in the guest when the other USB-C port
is exposed to the guest. Both tps6598x share unfortunately an interrupt
line.

* Fix correctness issues (ranges could end up overlapping)
* Split ranges instead of merging them on overlap (previously a single
  range overlapping everything would reduce the lookup to a linear
  search over all ranges)
* Support removal and generic mutations by splitting out a generic
  RangeMap class that can be used with arbitrary values/collections
