[PATCH] hw/cxl: Fix opaque type interpret wrongly

[Li Zhijian]

void cxl_component_register_block_init(Object *obj,
                                       CXLComponentState *cxl_cstate,
                                       const char *type)
{
    ComponentRegisters *cregs = &cxl_cstate->crb;
...
    memory_region_init_io(&cregs->cache_mem, obj, &cache_mem_ops, cregs,
                          ".cache_mem", CXL2_COMPONENT_CM_REGION_SIZE);

Obviously, opaque should be pointer to ComponentRegisters.
Fortunately, cregs is the first member of cxl_state, so their values are
the same.
