memory: renesas-rpc-if: Consolidate XSPI_CDTBUF0 updates in read path
Program the XSPI_CDTBUF0 fields used by the RPCIF_DATA_IN transfer path
through a single regmap_update_bits() call.
The existing code updates TRTYPE, DATASIZE, ADDSIZE and LATE using
multiple read-modify-write operations on the same register, even though
all field values are known before the transfer starts.
Build the register mask and value first, then perform a single register
update. This reduces register accesses and simplifies the transfer setup
without changing functionality.
