Rename floppy_type macros to make them more consistent with the scsi_type
macros, which are named after classes of models with similar memory maps.
The documentation for LC-class machines has the IO devices at offsets
from $50F0 0000. Use these addresses (consistent with mac_scsi resources)
because they may not be aliased elsewhere in the memory map, e.g. at
offsets from $5000 0000.
Add comments with controller type information from 'Designing Cards and
Drivers for the Macintosh Family', relevant Developer Notes and
http://mess.redump.net/mess/driver_info/mac_technical_notes
Adopt phys_addr_t to avoid type casts.

Hi Geert,
I just noticed that this patch didn't appear in v5.2. Would you please
take a look?

Hi Finn,
Thanks for your patch!

I guess the others do have aliases at 0x50000000? ...

... so that's why you change them from 0x50fxxxxx to 0x500xxxxx?
If that is correct, please mention that in the patch description.
Thanks!

Right. Otherwise mac_scsi wouldn't work. See also, arch/m68k/mac/config.c:
* GMFH says that $5000 0000 - $50FF FFFF "wraps
* $5000 0000 - $5001 FFFF eight times" (!)
* mess.org says IIci and Color Classic do not alias
* I/O address space.
