[PATCH] spi: rockchip: return 0 if tx_buf and rx_buf are NULL

To do so, spi communication can use an empty buf to pull up CS. This patch merged from ChromiumOS tree. Cros_ec use this function to turn off CS and add a delay to ensure the rising edge doesn't come too soon after the end of the data. Tested-by: Doug Anderson Signed-off-by: Doug Anderson Signe
