SPI devices use the spi_device_id for module autoloading even on
systems using device tree, after commit 5fa6863ba692 ("spi: Check
we have a spi_device_id for each DT compatible"), kernel warns as
follows since the spi_device_id is missing:
SPI driver s6d27a1-panel has no spi_device_id for samsung,s6d27a1
Add spi_device_id entries to silence the warning, and ensure driver
module autoloading works.
