It seems the flash needs no special configuration. IIUC it can be driven
entirely based on SFDP data. In that case, I don't think there is a need
for an entry at all. The generic SFDP-based driver should already be
enough for your flash. Just add a "jedec,spi-nor" node to your DT and it
should work.
