[IDE] Fix build bug

[Ralf Baechle <ralf@linux-mips.org>]

  CC      drivers/ide/pci/generic.o
drivers/ide/pci/generic.c:52: error: __setup_str_ide_generic_all_on causes a
+section type conflict

This sort of build error is becoming a regular issue.  Either all or non
of the elements that go into a particular section of a compilation unit
need to be const.  Or an error may result such as in this case if
CONFIG_HOTPLUG is unset.

Maybe worth a check in checkpatch.pl - but certainly gcc's interolerance
is also being less than helpful here.
