rz1000: apply chipset quirks early (v2)
* Use pci_name(dev) instead of hwif->name in init_hwif_rz1000(). * init_hwif_rz1000() -> rz1000_init_chipset(). Update rz1000_init_one() to use rz1000_init_chipset() and add now required rz1000_remove(). * Remove superfluous ide_rz1000 chipset type. v2: * unsigned int rz1000_init_chipset() -> int rz1000_disable_readahead() per Sergei's suggestion.
