memory: renesas-rpc-if: Consolidate XSPI_CDTBUF0 updates in write path
Program the XSPI_CDTBUF0 TRTYPE, DATASIZE and ADDSIZE fields with a
single regmap_update_bits() call in the RPCIF_DATA_OUT transfer path.
The existing code updates these fields through three separate
read-modify-write operations even though all values are known before the
transfer request is issued. Combine the updates into a single register
access to reduce overhead and simplify the configuration sequence.
