spi: Updates for v5.5

Lots of stuff going on in the core for SPI this time around, the two big
changes both being around time in different forms:

- A rework of delay times from Alexandru Ardelean which makes the ways
in which they are specified more consistent between drivers so that
what's available to clients is less dependent on the hardware
implementation.
- Support for PTP timestamping of transfers from Vladimir Oltean,
useful for use with precision clocks with SPI control interfaces.
- Big cleanups for the Atmel, PXA2xx and Zynq QSPI drivers.
