atari_NCR5380: Remove RESET_BOOT, CONFIG_ATARI_SCSI_TOSHIBA_DELAY and CONFIG_ATARI_SCSI_RESET_BOOT
The atari_NCR5380.c core driver now takes care of bus reset upon driver initialization if required (same as NCR5380.c). Move the Toshiba CD-ROM support into the core driver, enabled with a host flag, so that all NCR5380 drivers can make use of it. Drop the RESET_BOOT macros and the ATARI_SCSI_RESET_BOOT and ATARI_SCSI_TOSHIBA_DELAY Kconfig symbols, which are now redundant. Remove the atari_scsi_reset_boot(), mac_scsi_reset_boot() and sun3_scsi_reset_boot() routines. None of this duplicated code is needed now that all drivers can use NCR5380_maybe_reset_bus(). This brings atari_scsi, mac_scsi and sun3_scsi into line with all of the other NCR5380 drivers. The bus reset may raise an interrupt. That would be new behaviour for atari_scsi only when CONFIG_ATARI_SCSI_RESET_BOOT=n. The ST DMA interrupt is not assigned to atari_scsi at this stage, so CONFIG_ATARI_SCSI_RESET_BOOT=y may well be problematic already. Regardless, do_reset() now raises and clears the interrupt within local_irq_save/restore which should avoid problems.
