Not all LJCA chips implement SPI and on chips without SPI reading the SPI descriptors will timeout.
On laptop models like the Dell Latitude 9420, this is expected behavior and not an error.
Modify the driver to continue without instantiating a SPI auxbus child, instead of failing to probe() the whole LJCA chip.

Nit, stable is not needed as the above commit only ended up in 6.7-rc1, nothing older. I'll drop it when I queue this up, thanks!
