sgiioc4: fix messages
Fix several issues with the log messages printed by ide_dma_sgiioc4() and
sgiioc4_ide_setup_pci_device():
- IOC4 registers are memory-mapped but the "BM-DMA at" format corresponds to
I/O mapped registers;
- "%p" format specifiers and type casts used to print non-pointer values;
- using KERN_INFO log level for the error message;
- 'hwif->name' printed as drive's name.
While at it, also:
- return more fitting -EBUSY if request_mem_region() fails;
- make the error message style consistent;
- fix indentation, put the printk() facility and message on the same line;
- use comparisions with NULL instead of ! operator..
