Revert "comedi: add HAS_IOPORT dependencies"

This reverts commit b5c75b68b7ded84d4c82118974ce3975a4dcaa74.

The commit makes it impossible to select configuration options that
depend on COMEDI_8254, COMEDI_DAS08, COMEDI_NI_LABPC, or
COMEDI_AMPLC_DIO200 options due to changing 'select' directives to
'depends on' directives and there being no other way to select those
codependent configuration options.
