Subject: [PATCH] memory: RENESAS_RPCIF should select RESET_CONTROLLER

The Renesas RPC-IF driver calls devm_reset_control_get_exclusive(),
which returns -ENOTSUPP if CONFIG_RESET_CONTROLLER is not enabled.
Even if this error is ignored, later calls to reset_control_reset() will
fail with a scary WARN_ON() backtrace.
