PCI: switchtec: Add missing __iomem and __user tags to fix sparse warnings

Browse Source 
Fix a number of missing __iomem and __user tags in the ioctl functions of
the switchtec driver. This fixes a number of sparse warnings of the form:

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

Fixes: 52eabba5bc ("switchtec: Add IOCTLs to the Switchtec driver")
