PCI: Make PCI_ROM_ADDRESS_MASK a 32-bit constant
commit 76dc52684d0f72971d9f6cc7d5ae198061b715bd upstream.
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().
