npcx: driver: SPI: extend driver to support concurrent mode
This CL extends the SPI controller driver to support the concurrent
transaction:
- if the parameter "rxlen" is set to SPI_READBACK_ALL when
spi_transaction() is called, the received data during the transmission
phase should be stored in the "rxdata" buffer.
BRANCH=none
BUG=b:268286582
TEST=Loopback test on the npcx9 EVB, make sure the received data in the
rxdata buffer is the same as that in the txdata buffer.
