spi: xilinx: Use pdev->id instead of pdev->dev.id for the SPI bus number
The Xilinx SPI driver initializes the bus_num field of the SPI master to pdev->dev.id. pdev->dev.id is always 0 for platform devices which causes bus number conflicts for the SPI controller when creating multiple device instances of the driver. Instead use pdev->id which will have the assignt platform device id. If the device is instantiated via devicetree pdev->id is -1 which will cause the SPI core to dynamically assign a id (or use the id defined via a alias in the devicetree).
