intel-iommu: fix compile warnings

Impact: cleanup

I got the following warnings on IA64:

  linux-2.6/drivers/pci/intel-iommu.c: In function 'init_dmars':
  linux-2.6/drivers/pci/intel-iommu.c:1658: warning: format '%Lx' expects type 'long long unsigned int', but argument 2 has type 'u64'
  linux-2.6/drivers/pci/intel-iommu.c:1663: warning: format '%Lx' expects type 'long long unsigned int', but argument 2 has type 'u64'

Another victim of int-ll64.h versus int-l64.h confusion between platforms.

->reg_base_addr has a type of u64 - which can only be printed out
consistently if we cast its type up to LL.

[ Eventually reg_base_addr should be converted to phys_addr_t, for which
  we have the %pR printk helper - but that is out of the scope of late
  -rc's. ]
