axi_dmac: Correctly handle shutdown for the request splitter
...
We need to make sure to not prematurely de-assert the s_valid signal for the
request splitter when disabling the DMAC. Otherwise it is possible that
under certain conditions the DMAC is disabled with a partially accepted
request and when it is enabled again it will continue in an inconsistent
state which can lead to transfer corruption or pipeline stalls.

axi_dmac: Use internal enable signal for the request generator
...
All components should use the internal 'do_enable' signal instead of the
external 'enable' signal. The former correctly incorporates the shutdown
sequence and does not get asserted again until the shutdown has been
completed. Using the external signal can cause problems when it is disabled
and enabled again in close proximity.

axi_dmac: request_generator: Stop generating requests when disabled
...
Currently when the DMAC gets disabled the request_generator will still
generate all remaining burst requests for the currently active transfer.
While these requests will be ignored by the source and destination component
this can still take a fair amount of time for long transfers.
So just stop generating burst requests once the DMAC is being disabled.

dmac: fifo_inf: Handle overflow and underflow correctly
...
Refactor the fifo_inf modules to always correctly generate the underflow and
overflow status signals. Before it was possible that in some cases they
were not generated when they should have been.

The adc_wcnt_int must be synchronized to adc_wr. The adc_dwr signal pulse width was to long,
it needs to be just one adc_clk cycle.
