spi: pxa2xx-pci: Remove unused code

pcim_iomap_table() can't fail when called after pcim_iomap_regions(). Moreover,
we already dereference returned value and kernel will crash if it is not
correct.

Remove obvious leftover of commit 0202775bc3a2 ("spi/pxa2xx-pci: switch to use
pcim_* interfaces").
