eb466796d8 fw.dcp: Add some stubs needed for modesetting 
This isn't enough to set the video mode yet but it gets us further. I
think allocate_memory/map_buf/powerOnDART need real implementations,
otherwise setting a video mode crashes the DCP in an APIODMA interrupt
handler, whatever that is.

f8110dd409 hv_exc: Handle M1RACLES mitigation here due to 12.0 spam 
macOS 12.0 added a silly ineffective "mitigation" that clears the
register on every context switch. This doesn't actually mitigate
anything, but it does make this sysreg trap performance-critical,
so we have to move its handling into the C side.

1d932888f9 Add command categories to reduce command clutter 
Based on a suggestion from Ludwig Schubert it now uses the inspect class
to generate signatures of the functions for the help messages and
the qualified names which is a big improvement.

Also greatly reduced the clutter by putting the class functions into seperate
categories based on their class name. Now the top level help fits on one
page making it much more readable.

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.
