[PULL 21/24] hw/riscv/riscv-iommu: Remove definition of RISCVIOMMU[Pci|Sys]Class

[Philippe Mathieu-Daudé]

From: Zhenzhong Duan <zhenzhong.d...@intel.com>

RISCVIOMMUPciClass and RISCVIOMMUSysClass are defined with missed
parent class, class_init on them may corrupt their parent class
fields.

It's lucky that parent_realize and parent_phases are not initialized
or used until now, so just remove the definitions. They can be added
back when really necessary.
