spi: pxa2xxx: change "no DMA channels..." msg from debug to warning ...
Change the type of the diagnostic message:
"no DMA channels available, using PIO"
from debug to warning.
The lack of an available DMA channel is very important regard the
spi-pxa2xx performance. The transfer speed can be reduced more than 50%.
So it is very important to warn the user about this, without enabling
the full SPI debug with CONFIG_SPI_DEBUG.
Moreover, enabling the full SPI debug only to enable this specific
debug message, the dmesg buffer fills quickly with a lot of
repetitive information during the SPI data transfer.
This cause the loss of all the first important messages
written during the initialization.
