Eugeniy Paltsev bcdcb3e61e DW SPI: add option to use external gpio for chip select 
DW SPI internal chip select management has limitation:
it hold CS line in active state only when the FIFO is not
empty. If the FIFO freed before we add new data the SPI transaction will
be broken.

So add option to use external gpio for chip select. Gpio can be added
via device tree using standard gpio bindings.
