It seems messy to me that PCMCIA lives outside of the LOWLEVEL section.

Given that the number of users that rely on PCMCIA for their system disk
is probably pretty low, I think I'm leaning towards cleaning things up
instead of introducing a nonsensical top level option.

Or even better: Get rid of SCSI_FDOMAIN as a user-visible option and
select it if either of the PCI/ISA/PCMCIA drivers are enabled.
