[Mika Westerberg]

Fix following warnings seen when compiling 64-bit:

drivers/spi/spi-pxa2xx.c: In function âmap_dma_buffersâ: drivers/spi/spi-pxa2xx.c:384:7: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
drivers/spi/spi-pxa2xx.c:384:40: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
drivers/spi/spi-pxa2xx.c: In function âpxa2xx_spi_probeâ:
drivers/spi/spi-pxa2xx.c:1572:34: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
drivers/spi/spi-pxa2xx.c:1572:34: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
drivers/spi/spi-pxa2xx.c:1572:34: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
drivers/spi/spi-pxa2xx.c:1572:27: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
