Details:

with shifted data in fifo.

soc/cores/spi_mmap: adjust CSR mapping to better suit drivers
...
Currently the TX_RX_ENGINE CSR register lives below the
slot registers which are dynamic in length (based on how
many slots (chip selects) are configured in the gateware).
Move the TX_RX_ENGINE CSR to above the SLOT configuration
registers so TX_RX_ENGINE never moves.
This makes for an easier and cleaner driver.
