m1n1.adt: introduce yet another DAPFT8110 variant

When I tried to use the proxyclient shell, I got:
"Exception parsing /device-tree/arm-io/dart-dcp.dapf-instance-0 value […]"

I laid out the hex dump in a text editor, and added line breaks every
56 bytes (the former size of DAPFT8110B):

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.
