[PATCH v2 4/4] PCI: cadence: Fix to read 32-bit Vendor ID/Device ID property from DT

[Kishon Vijay Abraham I]

The PCI Bus Binding specification (IEEE Std 1275-1994 Revision 2.1 [1])
defines both Vendor ID and Device ID to be 32-bits. Fix
pcie-cadence-host.c driver to read 32-bit Vendor ID and Device ID
properties from device tree.
