spi/spi-pl022: Use GFP_ATOMIC for allocation from tasklet

Browse source

tasklets don't allow invocation to sleeping routines. In configure_dma()
routine, sg_alloc_table() was called with GFP_KERNEL flag and so this causes
crash when called from tasklet.

Replace GFP_KERNEL with GFP_ATOMIC to get this fixed.
