[SCSI] advansys: Convert to EISA driver model
- Switch EISA probing to the driver model - Remove some now-unused macros and functions - Update the FIXME now that we use the correct driver model probing API Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>hifive-unleashed-5.1
