staging: comedi: ii_pci20kc: iobase and ioaddr are void __iomem *

The iobase variables in struct pci20xxx_subdev_private and ioaddr
variable in struct pci20xxx_private should be void __iomem * not
void *.

This quiets a lot of sparse warings for the writeb and readb calls
like:

warning: incorrect type in argument 1 (different address spaces)
   expected void const volatile [noderef] <asn:2>*addr
   got void *<noident>

warning: incorrect type in argument 2 (different address spaces)
   expected void volatile [noderef] <asn:2>*addr
   got void *
