For sbc8360_wdt this causes a compile error on UML once inb()/outb() helpers become conditional. For sbc7240_wdt this causes no such errors with UML because this driver depends on both x86_32 and !UML. Nevertheless add HAS_IOPORT as a dependency for both drivers to be explicit and drop the !UML dependency for sbc7240_wdt as it is now redundant since UML implies no HAS_IOPORT.
