Input: ads7846 - 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()")
