sgiioc4: remove maskproc() method
Since the maskproc() method calls either mirror the interrupt en/disable via the nIEN bit of the device control register done by the IDE core before issuing a command or unmask the interrupt after a command executed in polled mode (when interrupt is already not expected), it is pointless to implement this method by manipulating the nIEN bit...
