spi: Updates for v5.1

A fairly quiet release for SPI, the biggest thing is the conversion to
use GPIO descriptors which is now 90% done but still needs some
stragglers converting.

 - Support for inter-word delays.
 - Conversion of the core and most drivers to use GPIO descriptors for
   GPIO controlled chip selects.
 - New drivers for NXP FlexSPI and QuadSPI, SiFive and Spreadtrum.
