[PATCH] powerpc: fsl_pamu_domain: Fix build error

[Pranith Kumar]

Fix build failure in fsl_pamu_domain.o caused as follows

drivers/iommu/fsl_pamu_domain.c: In function 'pamu_domain_init':
drivers/iommu/fsl_pamu_domain.c:1103:17: error: 'pci_bus_type' undeclared
(first use in this function)
drivers/iommu/fsl_pamu_domain.c:1103:17: note: each undeclared identifier is
reported only once for each function it appears in
make[2]: *** [drivers/iommu/fsl_pamu_domain.o] Error 1
make[1]: *** [drivers/iommu] Error 2
make: *** [drivers] Error 2

We fix this by trying to dereference pci_bus_type only if CONFIG_PCI is defined.
