ide: remove chipset field from hw_regs_t

* Convert host drivers that still use hw_regs_t's chipset field to use the one in struct ide_port_info instead. * Move special handling of ide_pci chipset type from ide_hw_configure() to ide_init_port(). * Remove chipset field from hw_regs_t. While at it: - remove stale comment in delkin_cb.c There should be no functional changes caused by this patch.
