[PATCH v2 04/10] drm/panel: novatek, nt39016: Silence no spi_device_id warning

From: Wei Yongjun <weiyongjun1 at huawei.com>

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 nt39016 has no spi_device_id for kingdisplay,kd035g6-54nt

Add spi_device_id entries to silence the warning, and ensure driver
module autoloading works.
