Restrict the clk/cmd scan to 1/2 tCK since the full scan is not required
and in some cases can compromise the calibration with the wrong best clk/cmd
value selection.
This should also allow using cmd_latency=0 in all cases.

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"})

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.
