Input: applespi - use new 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).
