The RPC SPI DT node is now part of mainline Linux DT, remove the duplicate content from U-Boot DT extras. The SPI flash DT node name has been changed from "spi-flash@0" to "flash@0", reflect this change in this patch. Retain "bank-width" and "num-cs" DT properties which are used by U-Boot. Retain "spi-rx-bus-width" and "spi-tx-bus-width" DT properties to indicate the bus should always be operated in 1-1-1 mode as the U-Boot RPC SPI driver does not support higher bus width modes yet.
