ANDROID: spi: of: Populate fwnode in of_register_spi_device

Browse Source 
This allows the of_devlink feature to work across spi devices too.  This
avoid unnecessary probe deferrals of spi devices, defers consumers of
spi devices till the spi devices probe, and allows spi drivers to
implement sync_state() callbacks.
