memory: renesas-rpc-if: Consolidate command setup register programming

Simplify the command setup sequence in xspi_manual_xfer_impl() by
combining updates to XSPI_CDCTL0 and XSPI_CDTBUF0.

Clear the TRNUM and TRREQ fields in XSPI_CDCTL0 with a single
regmap_update_bits() call. Likewise, program the command, command size
and address size fields in XSPI_CDTBUF0 with a single regmap_write(),
eliminating the subsequent ADDSIZE update. The intermediate write of
zero to XSPI_CDABUF0 is also redundant, as the register is immediately
programmed with the transfer address.
