[v2,1/2] xilink_zynq: Add various missing unimplemented devices

Commit Message

Chao Liu Sept. 27, 2024, 8:51 a.m. UTC

Add PMU, CAN, GPIO, I2C, and other as unimplemented devices.

Remove a ignore_memory_transaction_failures concurrently.

This allows operating systems such as Linux to run emulations such as xilinx_zynq-7000
