staging: comedi: Kconfig: cleanup depends on logic

All of the config options for comedi depend on COMEDI being
selected. Wrap everything in an 'if COMEDI/endif' block and
remove all the individual 'depends on COMEDI' in the Kconfig.

Also, remove the redundant && ISA/PCI/PCMCIA/USB for the if
blocks with those driver types.
