Currently, I2C is not available to PL by default assembly variant (R584, R585). It seems that that should not be the case.

However, mounting those will require some arbitration in Zynq (between PS I2C and PL I2C) or at least careful usage of I2C in projects. This should be included in final documentation.

We don't actually need PS access to I2C. One can attach I2C IP core and gain access from the PS.
I'd make resistors connecting I2C and PS DPN by default.

PL access is set by default, PS is with DNP resistors.
