Robert Jördens d97ee3f0c4 Revert "pounder timestmper: don't use DMA" 
This reverts commit 26b261364f.

First needs to reduce capture rate to batch interval. Otherwise it's
jittery due to polling alignment.

Robert Jördens 26b261364f pounder timestmper: don't use DMA 
* One sample per batch is typical and sufficient.
* DMA has more overhead than direct read for one sample.

Robert Jördens 2368a4f6ed pounder: enum for gpio ext pins 
This is currently unused but it's better to have enums than
a set of assorted constants.

Robert Jördens 3616f1fa5a pounder: fix attenuator indices (latch and shiftreg) 
Before the discriminant was used despite being a compiler implementaiton
detail. This now fixes the discriminant to match byte index in the attenuator
shift register and latch-enable index of the gpio extender.

Robert Jördens fc78b087ee attenuators: use robust latching sequence 
To ensure that eatch call to latch() generates a rising edge, first
assert low, then high, not the other way round.

David Nadlinger 4606d93900 Update stm32h7xx-hal 
I haven't done any runtime tests using Pounder, but it seems
like the API change is just a consequence of making the QSPI
address width runtime-configurable.
