spi: Update swnode based SPI devices to use the fwnode name

Update the name for software node based SPI devices to use the fwnode
name as the device name. This is helpful since swnode devices are
usually added within the kernel, and the kernel often then requires a
predictable name such that it can refer back to the device.
