Fill in register definitions and extend the driver code to introduce
support for RX channels. This involves change of channel numbering.

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()

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.

This should not be required but it looks like the 12.1 ANS2 firmware
complains when NVME_CC.EN is cleared before the IO queues have been
deleted.

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.

When loading m1n1.bin, SEPFW follows m1n1 and thus will show up at
the payload offset if there are no payloads.

This drops the tx/rxcookie and accepts TYPE_NOTIFY in addition to
TYPE_REPLY for command replies to make the DCP code also work on 11.x.
It'll still complain about an unexpected message during init but work.

s/IDLE/HIBERNATE/ to keep in sync with the Linux driver and then
hibernate DCP but send ANS2 to sleep to allow reusing both.

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.
