[U-Boot] [PATCH] pci: fix some warnings related to assumptions about

[Kumar Gala]

The following commit introduced some warnings associated with using
pci_addr_t instead of a proper 32-bit data type.

    pci: fix errant data types and corresponding access functions

On some platforms pci_addr_t is defined as a 64-bit data type so its not
proper to use with pci_{read,write}_config_dword.
