PCI: Make PCI_ROM_ADDRESS_MASK a 32-bit constant
A 64-bit value is not needed since a PCI ROM address consists in 32 bits. This fixes a clang warning about "implicit conversion from 'unsigned long' to 'u32'". Also remove now unnecessary casts to u32 from __pci_read_base() and pci_std_update_resource(). Signed-off-by: Matthias Kaehlcke <mka@chromium.org> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
