spi: npcm-fiu: support dual and quad UMA writes

The manual page-program path used the UMA command byte for the
first byte of each continuation chunk. That forced command-lane
semantics onto chunked writes and blocked dual/quad payload
writes.

Switch continuation chunks to data-only UMA transactions so WDBPCK
controls the payload bus width.
