staging: comedi: jr3_pci: use pci_ioremap_bar()
Use pci_ioremap_bar() to ioremap the PCI resources. That function
just takes the pci device and a bar number. It also has some
additional sanity checks to make sure the bar is actually a
memory resource.
This also makes sure that the entire PCI bar is ioremap'ed instead
of assuming the size of the bar.
