The adis16460 device requires a stall time between SPI
transactions (during which the chip select is inactive),
with a minimum value equal to 16 microseconds.
This commit adds 'spi-cs-inactive-delay-ns' property, which should
indicate the stall time between consecutive SPI transactions.
The specified minimum time may not be sufficient for all
configurations.
