PCI: switchtec: Add missing __iomem tag to fix sparse warnings 

Fix a missing __iomem tag in the init_pfn() function. This fixes a sparse
warning of the form:

  $ make C=2 drivers/pci/switch/
  drivers/pci/switch/switchtec.c:... incorrect type assignment(different address spaces)

Fixes: 080b47def5 ("MicroSemi Switchtec management interface driver")
