pch_dma: Use GFP_ATOMIC because called from interrupt context

commit 5c1ef59168c485318e40ba485c1eba57d81d0faa upstream.

pdc_desc_get() is called from pd_prep_slave_sg, and the function is
called from interrupt context(e.g. Uart driver "pch_uart.c").
In fact, I saw kernel error message.
So, GFP_ATOMIC must be used not GFP_NOIO.
