This makes the cpu mode of the driver available outside of an FSL SOC
and even powerpc environment. Furthermore, this adds support for the
mostly register-compatible SPICTRL core from the GRLIB VHDL IP core
library normally running on SPARC.
This effort is split up in several patches for clarity o
This is needed for a device in SPI_CS_HIGH mode that otherwise could start out
active for the first transaction.

This makes the spi-fsl-spi driver usable in CPU mode outside of an FSL_SOC and
even an powerpc environment by moving CPM mode functionality to a separate file
that is only compiled and linked in an FSL_SOC environment and adding some
ifdefs to hide types and functions or provide alternatives.

This adds support for the mostly register-compatible SPICTRL cores from the
GRLIB VHDL IP core library from Aeroflex Gaisler. They are normally running on
SPARC. A different entry in of_fsl_spi_match matches this core and indicates a
different hardware type that is used to set up different function

This relies upon of_spi_register_master to find out which gpios to use.
