Previously, in #17818, a spi_device OTTF console was added to facilitate manufacturing flows that require used of higher speed IO (than is available with UART). When generic mode was removed in #20856, this feature was also removed, since it made use of generic mode.
To facilitate manufacturing flows for Earlgrey PROD, a new spi_device OTTF console should be implemented using the SPI mailbox.
