[PATCH v4 2/3] spi: Add a mechanism to use the fwnode name for the SPI device

[Charles Keepax <ckeepax@opensource.cirrus.com>]

Add a mechanism to force the use of the fwnode name for the name of the
SPI device itself. This is useful when devices need to be manually added
within the kernel.

Changes since v3:
 - Always name swnode SPI devices after the node name

Thanks,
Charles
