Subject: [PATCH v3 4/8] 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:
  [    0.832958] Unhandled fault: external abort on non-linefetch (0x1008) at 0x90b5f848

Select PM and PM_GENERIC_DOMAINS for ARCH_RZN1
