Identifiers in C are case sensitive. Rename the Qsys led_pio component to LED_PIO. Don't worry about the nios warning. It is just telling you that a newer NIOS is available. The error with IOWR_ALTERA_AVALON_PIO_DATA is because you haven't included the .h file for the GPIO core. I don't recall its name at the moment, but you should be able to find example code that uses it.
