libretroadmin a29b73f01a tests: record what spr/normal claims, and why it is not scored
tests/dma/spr/normal.expected is about the DMA registers rather than the
transfer: SADR keeps bits 4 to 13, so its 0x81234028 reads back as 0x20,
and MADR drops bit 31, which is why its own harness reports that the
transfer "did not accept MADR: 80000000". Dmac.cpp's write path applies
0x3FF0 and 0x7FFFFFFF, so both claims hold; that was checked by reading
it.

I wrote it as a scored check first and threw that away. The cases were
"input & mask == expected" with the mask copied out of Dmac.cpp and the
expected value copied out of the capture, which compares two constants I
had transcribed and can only fail if I mistyped one. It passed 6 of 6 and
proved nothing about the emulator: driving the real write path needs the
hardware register file and its dispatch, which this harness does not have.

So it is recorded as an inspection instead. That is the same call already
made in this series for the arm64 switch dispatch and the MDEC status
register -- an inspection recorded as an inspection is worth more than a
check that cannot fail, and a score of 6 of 6 sitting in the output would
have implied coverage nothing was providing.
