64d8f9d1b3 m1n1.loadobjs: Add util for loading objects on target 
For those of us who can't write assembly but still need to run code on
the other side.

  >>> from m1n1.loadobjs import *
  >>> lp = LinkedProgram(u)
  >>> lp.debug_printf("hello from the other side (%d)\n", 42)
  TTY> hello from the other side (42)
  0x1f
  >>> lp.load_obj("build/test.o")
  >>> lp.test()
  TTY> hello from loaded object
  0x19
  >>> lp.clear_objs()

0d35eb3da7 m1n1.proxyutils: Wrap ADT base to 64 bits 
This works around a wraparound issue when the virt base ends up causing
the ADT address to go negative, when on 12.1+ using a dummy virt base.

cad8df30ce nvme: delete IO SQ/CQ when shutting down 
This should not be required but it looks like the 12.1 ANS2 firmware

deleted.

2ee920d229 sart: fix for 12.1 
Looks like Apple decided to change the compatible to sart,coastguard and rely
on the sart-version ADT property to differentiate between M1 and M1 Pro/Max
instead. sart-version is already present in the 11.x ADT so let's just
always decide based on that.

fbc15bd77c payload: Consider an IMG4 blob as the end of payloads 
When loading m1n1.bin, SEPFW follows m1n1 and thus will show up at
the payload offset if there are no payloads.

00404e9bc3 afk: propagate failures in afk_epic_rx correctly 
If the co-processor crashes afk_epic_poll will always fail which results
in afk_epic_rx getting stuck in an infinite loop calling afk_epic_poll
again and again.
This happens with e.g. old/incompatible DCP firmware.
Make sure the m1n1 proxy still works in those cases by propagating the
error correctly.
