iommu/dma: Fix compile warning in 32-bit builds 



commit 7154cbd31c2069726cf730b0ed94e2e79a221602 upstream.

Compiling the recent dma-iommu changes under 32-bit x86 triggers this
compile warning:

drivers/iommu/dma-iommu.c:249:5: warning: format ‘%llx’ expects argument of type ‘long long unsigned int’, but argument 3 has type ‘phys_addr_t’ {aka ‘unsigned int’} [-Wformat=]

The reason is that %llx is used to print a variable of type
phys_addr_t. Fix it by using the correct %pa format specifier for
phys_addr_t.
