It might be that the board is booting without QE, e.g. currently U-Boot doesn't support QE for P1021MDS boards, which means that QE isn't initialized, and so the board hangs early at boot. This patch fixes the issue by marking QE as disabled and checking the state in the probing code. U-Boot should fixup the state if it initialized the QE.

This patch excludes the DIU, SSI, and MMC/SD drivers. Only a 36-bit DTS is provided. Update mpc86xx_smp_defconfig and mpc85xx_defconfig to support the P1022DS. This means enabling 64-bit physical address support, increasing the maximum zone order to 12 (to allow the DIU driver to allocate large chunks), and clean up the audio options to disable the deprecated OSS support.
