soc: renesas: rzn1: Select PM and PM_GENERIC_DOMAINS configs

PM and PM_GENERIC_DOMAINS configs are required for RZ/N1 SOCs.
Without these configs, the clocks used by the PCI bridge are not
enabled and so accessing the devices leads to a kernel crash:

    Unhandled fault: external abort on non-linefetch (0x1008) at 0x90b5f848
