cores/cpu/zynq7000: improve methods to pass provide/pass configuration to PS7.
...
User can now only use set_ps7 and provides the .xci file, preset file or/and additional configuration:
To use a .xci file, in the design do:
self.cpu.set_ps7(xci="ps7.xci")
To use a preset:
self.cpu.set_ps7(preset="preset_name")
To use a config dict:
self.cpu.set_ps7(name="ps7_name", config={"param0": "0", "param1": "1"})
It's also possible to use preset and then pass and additionnal config dict:
self.cpu.set_ps7(preset="preset_name")
self.cpu.add_ps7_config({"param0": "0", "param1": "1"})
or all at once:
self.cpu.set_ps7(preset="preset_name", config={"param0": "0", "param1": "1"})

integration/soc/SoCIRQHandler: be sure IRQs can only be added when enabled.
...
This prevents adding peripherals that requires IRQ support to SoC not supporting
them. Enabling is done automatically when a CPU with interrupt support is added,
but this can also be added manually.

rocket: Fix UB due to optimised away DFFs
...
As both clock and async reset for the debug DFFs were 0, and there was
no initial value on them, they were being validly optimised away by
newer Yosys versions to 1'bx which was propagating into and breaking the
core.
This fixes the problem by tying the async resets to the CPU reset
signal.

tools/remote/comms: base CommXY on CSRBuilder to allow using Comms directly in python scripts.
...
This way, user scripts can be use RemoteClient (communicating with the Server that has
already been opened on the right interface) or directly use CommXY in the scripts.
Using RemoteClient is more generic but can be slower (due to the Etherbone encoding between
the client and server). On fixed configuration using CommXY directly can then be faster
and also avoid manual opening of the server.
