Various U-Boot adoptions/extensions to MTD/NAND/UBI did not take buffer alignment into account which led to failures of the following form:
ERROR: v7_dcache_inval_range - start address is not aligned - 0x1f7f0108 ERROR: v7_dcache_inval_range - stop address is not aligned - 0x1f7f1108

Changes in v2: run it through checkpatch.pl and fix long lines

As per discussion on v1, this isn't enough to guarantee that the stop address will be aligned. There needs to be a wrapper around memalign() that cache- aligns the size as well.
