ide: add ->chipset field to ide_pci_device_t
Add ->chipset field to ide_pci_device_t and use it in ide_hwif_configure()
to set hwif->chipset. Convert cmd64x, cy82c693, rz1000 and trm290 host
drivers to use this new ability.
While at it define hwif_chipset_t as u8 to save some space in hw_regs_t,
ide_hwif_t and ide_pci_device_t instances.
