spi-topcliff-pch: Fix probing when DMA mode is used
If during registering SPI master due to SPI device probing a SPI transfer
is issued the DMA buffers are not allocated yet.
This fixes the following oops:
pch_spi 0000:02:0c.1: enabling device (0000 -> 0002)
pch_spi 0000:02:0c.1: master is unqueued, this is deprecated
BUG: unable to handle kernel NULL pointer dereference at (null)
