The restricted CXL host (RCH) error handler will log protocol errors using AER and RAS status registers. The AER and RAS registers need to be virtually memory mapped before enabling interrupts. Create the initializer function devm_cxl_setup_parent_dport() for this when the endpoint is connected with the dport. The initialization sets up the RCH RAS and AER mappings. Add 'struct cxl_regs' to 'struct cxl_dport' for saving a pointer to the RCH downstream port's AER and RAS registers.
