iio: adc: mcp320x: 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).

[1] commit bebcfd272d ("spi: introduce `delay` field for
`spi_transfer` + spi_transfer_delay_exec()")
