The Anbernic RG35XX devices use an SPI LCD panel from an unknown OEM,
with an NV3052C driver chip.

As discussed previously, the integrating vendor and device name are
preferred instead of the OEM serial. A previous patch corrected the
device tree binding and of_device_id in the NV3052C driver, however the
spi_device_id also needs correction.

Correct the spi_device_id for the RG35XX panel.
