hw/riscv: microchip_pfsoc: Hook the I2C1 controller
The latest SD card image [1] released by Microchip ships a Linux
kernel with built-in PolarFire SoC I2C driver support. The device
tree file includes the description for the I2C1 node hence kernel
tries to probe the I2C1 device during boot.
It is enough to create an unimplemented device for I2C1 to allow
the kernel to continue booting to the shell.
