A delay is needed each time the chip selected becomes inactive, even after burst data readings are performed. Currently, there is no delay added after a burst reading and in case a new SPI transfer is performed before the needed delay, the adis device becomes unresponsive until reset. This commit is adding the needed delay directly to the spi driver, using the cs_inactive parameter, in case it is not set and is removing the additional chip select change delay present in adis APIs to remove the double delay.
