[LinuxBIOS] CK804 hard_reset

One of the hard_reset() functions are wrong.  The two files don't agree:
  src/mainboard/tyan/s2895/auto.c
  src/southbridge/nvidia/ck804/ck804_reset.c

I think auto.c is correct, but I'd suggest changing it to:

static void hard_reset(void)
{
        set_bios_reset();

        pci_write_config32(PCI_DEV(1, CK804_DEVN_BASE + 0x1, 0), 0xe8, 0x0);

        /* hard reset */
        outb(0x0a, 0x0cf9); 
        outb(0x0e, 0x0cf9);

L1:     goto L1;            /* loop till reset */
}
