spi_mpc8xxx: Add support for QE DMA mode and CPM1/CPM2 chips
This patch adds QE buffer descriptors mode support for the
spi_mpc8xxx driver, and as a side effect we now support CPM1
and CPM2 SPI controllers.
That means that today we support almost all MPC SPI controllers:
- MPC834x-style controllers (support PIO mode only);
- CPM1 and CPM2 controllers (support DMA mode only);
- QE SPI controllers in CPU mode (PIO mode with shift quirks);
- QE SPI controllers in buffer descriptors (DMA) mode;
The only controller we don't currently support is a newer eSPI
(with a dedicated chip selects and a bit different registers map).
