spi: Fix invalid D channel response when flash interface is disabled
...
Issue: When the memory-mapped flash region is accessed while the flash
read mode is disabled (fctrl.en flag is clear), the SPI flash controller
generates an invalid response on the D channel.
This may cause the TileLink bus to deadlock.
Workaround: Software should avoid accessing the memory-mapped flash
region when the SPI controller is not in the flash read mode.
