Merge series "spi: fsi: Reduce max transfer size to 8 bytes" from Eddie James <eajames@linux.ibm.com>:
The security restrictions on the FSI-attached SPI controllers have
been applied universally to all controllers, so the controller can no
longer transfer more than 8 bytes for one transfer. Refactor the driver
to remove the looping and support for larger transfers, and remove the
"restricted" compatible string, as all the controllers are now
considered restricted.
