powerpc/85xx: Fix SWIOTLB initalization for MPC85xxMDS boards
The code inside '#ifdef CONFIG_QUICC_ENGINE' makes the mpc85xx_mds_setup_arch() return early if no QE nodes present, and so SWIOTLB is never initialized. This patch fixes the issue by moving SWIOTLB code above QE. Signed-off-by: Anton Vorontsov <avorontsov@mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
