m68k/mac: Fix scsi_type for Mac LC and similar models
Designing Cards and Drivers for the Macintosh Family, 3rd ed. on page 310 says that the I/O address space for the Mac LC is $50F0 0000 - $50FF FFFF. The developer notes for the Classic II, LC III and IIvx/IIvi give the same I/O address space. That means I've assigned the wrong platform resources to those Mac models. Fix the scsi_type initialization for the affected models, to restore the SCSI base address to its value prior to Linux 3.18. Also rename MAC_SCSI_CCL as MAC_SCSI_LC for the sake of correct chronology. Signed-off-by: Finn Thain <fthain@telegraphics.com.au> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
