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).
