ice: Use pci_get_dsn()
Replace the open-coded implementation for reading the PCIe DSN with pci_get_dsn(). The pci_get_dsn() function will perform two pci_read_config_dword calls to read the lower and upper config dwords. It bitwise ORs them into a u64 value. Instead of using put_unaligned_le32 to convert the value to LE32 format, just use the %016llX printf specifier. This will print the u64 correct, putting the most significant byte of the value first. Since pci_get_dsn() correctly orders the two dwords into a u64, this should produce equivalent results in less code.
