iio: imu: adis: use new `delay` structure for SPI transfer delays
In a recent change to the SPI subsystem [1], a new `delay` struct was added to replace the `delay_usecs`. This change replaces the current `delay_usecs` with `delay` for this driver. The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure that both `delay_usecs` & `delay` are used (in this order to preserve backwards compatibility). [1] commit bebcfd272df6485 ("spi: introduce `delay` field for `spi_transfer` + spi_transfer_delay_exec()") Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
