PCI: artpec6: Fix artpec6_pcie_cpu_addr_fixup() parameter name

The function pointer declaration for the cpu_addr_fixup() callback uses
"cpu_addr" as parameter name.

Likewise, the argument that is supplied to the function pointer when the
function is actually called is "cpu_addr".

Rename the artpec6_pcie_cpu_addr_fixup() parameter name to match
reality.
