[RFC 0/2] mpc5200: eliminate direct manipulation of shared registers from SPI driver

The mpc5200 PSC SPI driver driver directly manipulates the port_config
and the CDM registers on the mpc5200 which it should not do. port_config
should only be manipulated from within the board specific platform code
and the CDM registers are shared between multiple devices.
This patch eliminates the port_config manipulations and adds a common
routine for adjusting CDM settings. Boards using the SPI driver will
need to add the required port_config changes to either the boot firmware
or the platform code.
If there are no objections, I plan to ask Paulus to merge these in the
next couple of days.
