Also remove interrupt mapping, since it's unused without a CPU anyway.

8ecaaf0546 phy/{s7,us}rgmii.py: 
Recent modification that adds S7PLL that in return adds an AsyncResetSynchronizer inside XilinxClocking.

This actually creates a multi-driven net because there is another AsyncResetSync* being added in the Phys.

This change instantiates the PLL without a reset for now, leaving the CD reset intact.

cd413c5c20 phy/usrgmii.py: 
IDELAYE3 requires EN_VTC to be enabled for fixed mode time delay. This eliminates implementation time CRITICAL WARNINGs and ensures generating a bitfile.

57be29e68a global: pass data_width(dw) parameter to modules to prepare for 10Gbps/25Gbps links 
To support 10Gbps/25Gbps, the hardware stack will need to handle multiple bytes/clock cycle.
Pass dw to all modules to allow making use of it in the future. For now dw=8.
