PCI: cadence: Explicitly cast pointer returned by phys_to_virt() to __iomem

Cadence PCIe EP driver gets MSI-X table address (physical) from inbound
ATU and uses phys_to_virt() to get the virtual address (returns void *)
and store it in msix_tbl variable. However msi_tbl is declared with
"void __iomem *" since it has to be used with readl() to get the MSI
message address. This results in the following sparse warning:

sparse warnings: (new ones prefixed by >>)

pcie-cadence-ep.c:558:18: sparse: sparse: incorrect type in assignment (different address spaces)
pcie-cadence-ep.c:558:18: sparse:    expected void [noderef] <asn:2> *msix_tbl
pcie-cadence-ep.c:558:18: sparse:    got void *

Explicitly cast pointer returned by phys_to_virt() to __iomem to get
rid of the sparse warning.
