Fix Xtuple value generation

Remove space in from of and above Xtuple values.
This change just bring up consistency with other values
in DTS.

-               interrupts = < 0 5 4 0 6 4 >;
-               reg = < 0xf8891000 0x1000 0xf8893000 0x1000 >;
+               interrupts = <0 5 4 0 6 4>;
+               reg = <0xf8891000 0x1000 0xf8893000 0x1000>;

Add support for spi aliases

Aliases can direct order is spi bus naming.
And also remove bus-num property from spi node.

For example:
        aliases {
                ethernet0 = &ps7_ethernet_0;
                serial0 = &ps7_uart_1;
+               spi0 = &ps7_qspi_0;
        } ;
                ps7_qspi_0: ps7-qspi@e000d000 {
                        #address-cells = <1>;
                        #size-cells = <0>;
-                       bus-num = <0>;
                        compatible = "xlnx,ps7-qspi-1.00.a";
                        interrupt-parent = <&ps7_scugic_0>;
