Sergei Shtylyov 8108b88232 sgiioc4: kill useless address checks 
The driver performs a number of checks on the virtual/physical addresses which
would always evaluate as true (except ide_dma_sgiioc4() -- always false):

- for sgiioc4_init_hwif_ports(), its caller, sgiioc4_ide_setup_pci_device(),
  guarantees that 'ctrl_port' and 'irq_port' parameters are never 0;

- in sgiioc4_read_status(), we always read the IDE status register, so there's
  no need to check the register's address (must be a leftover from the times
  when this function implemented the INB() method);

- in ide_dma_sgiioc4(), 'dma_base' can never be 0 as IOC4_DMA_OFFSET is not 0.
