arm: mvebu: clearfog: update SPI flash DT description

All current ClearFog SOMs have the SPI flash populated. Enable SPI flash in
the device tree.

Add an alias to the SPI bus so that the 'sf' command can probe the flash on
bus 1.

Add the "spi-flash" compatible string to make the standard SPI flash driver
probe the device.
