Subject: spi: spi-fsl-dspi: Support SPI software timestamping in all non-DMA
 modes

Git-commit: 63669902f74a6133c209fc03109becf5a2141284
Patch-mainline: v5.7-rc1
References: jsc#SLE-12251

There's no reason to keep this .ptp_sts_supported property explicitly in
devtype_data, since it can be deduced from the operating mode alone.
