mtd: dataflash: Add device-tree SPI IDs

Browse Source 
Commit 5fa6863ba6 ("spi: Check we have a spi_device_id for each DT
compatible") added a test to check that every SPI driver has a
spi_device_id for each DT compatiable string defined by the driver
and warns if the spi_device_id is missing. The spi_device_ids are
missing for the dataflash driver and the following warnings are now
seen.

 WARNING KERN SPI driver mtd_dataflash has no spi_device_id for atmel,at45
 WARNING KERN SPI driver mtd_dataflash has no spi_device_id for atmel,dataflash

Fix this by adding the necessary spi_device_ids.
