On m3, these previouly expected-to-be-constant fields have exciting
non-constant values. This updates adt.py to allow them to be
non-constant. The second field is also really a flags field,
though i could not tell you all the flags involved.

Only observed with dcp/dptx in linux after initialisation and reset in
m1n1. On the initial startup dcp sends two D576 (hotPlug_notify_gated)
presumendly due to state confusion due to the multiple dptx
connections.

Looking at the patterns shared by all struct instances
(r0h = 3, r0l = 1, for example), each row appeared to be shifted one
byte to the left compared to its predecessor. This suggests that
DAPFT8110B has only three extra bytes of padding compared to
DAPFT8110.
So, here I introduce DAPFT8110C, a new variant, one byte shorter than
DAPFT8110B. Unlike DAPFT8110, there's no flag to differentiate
between these two variants, so we just have to guess based on what
divisor makes whole structs.

Since we directly trace the queue rptr/wptr memory locations, we don't
need the ASC tracing and this speeds things up quite a bit (without it,
Linux can get stuck in a pathological stats gathering loop without
making forward progress while traced).

This allows booting a kernel with the firmware cpio and a cpio
containing matching modules. The modules initramfs can be prepared from
the kernel source directory with:
`make dir-pkg && usr/gen_initramfs.sh -o initramfs_mod.cpio -u squash -g squash ./tar-install/lib/`
The modules are available in /modules/$(uname -r) and the initramfs can
handle modules in the same way as the vendor firmware to make them
available for itself and the main OS.
