So all the code here is built unconditionally...

but this is in an #ifdef?
I would suggest you do the opposite and leave the id table in there
but change the first check to
if (IS_ENABLED(CONFIG_OF) && np)
So the compiler can discard that code when CONFIG_OF is disabled.

Don't hardcode DMA masks like this, the mask should be set to a 32-bit
mask whenever the device is created, and the driver can override it
by calling dma_set_mask().
