ide: add device flags
Add 'unsigned long dev_flags' to ide_drive_t and convert bitfields to IDE_DFLAG_* flags. While at it: - IDE_DFLAG_ADDRESSING -> IDE_DFLAG_LBA48 - fixup some comments - remove needless g->flags zeroing from ide*_probe() There should be no functional changes caused by this patch.
