spi: pxa2xx: Allow 64-bit DMA

Browse Source 
Currently the 32-bit device address only is supported for DMA. However,
starting from Intel Sunrisepoint PCH the DMA address of the device FIFO
can be 64-bit.

Change the respective variable to be compatible with DMA engine
expectations, i.e. to phys_addr_t.
