Lars-Peter Clausen 374c49ff48 axi_dmac: axi_dmac_hw.tcl: Automatically detect clock domains
Qsys allows to query to query the clock domain that is associated with a
clock input of a peripheral. This allows to automatically detect whether
the different clocks of the DMAC are asynchronous and CDC logic needs to be
inserted or not.

Auto-detection has the advantages that the configuration parameters don't
need to be set manually and the optional configuration will be choose
automatically. There is also less chance of error of leaving the settings
in a wrong configuration when e.g. the clock domains change.

In case the auto-detection should ever fail configuration options that
provide a manual overwrite are added as well.
