ncr5380: Cleanup host info() methods
If the host->info() method is not set, then host->name is used by default. For atari_scsi, that is exactly the same text. So remove the redundant info() method. Keep sun3_scsi.c in line with atari_scsi. Some NCR5380 drivers return an empty string from the info() method (arm/cumana_1.c arm/oak.c mac_scsi.c) while other drivers use the default (dmx3191d dtc.c g_NCR5380.c pas16.c t128.c). Implement a common info() method to replace a lot of duplicated code which the various drivers use to announce the same information. This replaces most of the (deprecated) show_info() output and all of the NCR5380_print_info() output. This also eliminates a bunch of code in g_NCR5380 which just duplicates functionality in the core driver.
