Subject: [PATCH v1 2/2] spi: Populate fwnode in of_register_spi_device()

From: Daniel Mentz <danielmentz@...gle.com>

This allows the fw_devlink feature to work for spi devices
too.  This avoids unnecessary probe deferrals related to spi devices and
improves suspend/resume ordering for spi devices when fw_devlink=on.
