spi: fix return value check in dspi_probe()
...
In case of error, the function devm_ioremap_resource() returns
ERR_PTR() and never returns NULL. The NULL test in the return
value check should be replaced with IS_ERR().

spi:Add Freescale DSPI driver for Vybrid VF610 platform
...
The serial peripheral interface (SPI) module implemented on Freescale Vybrid
platform provides a synchronous serial bus for communication between Vybrid
and the external peripheral device.
The SPI supports full-duplex, three-wire synchronous transfer, has TX/RX FIFO
with depth of four entries.
This driver is the SPI master mode driver and has been tested on Vybrid
VF610TWR board.
