msm: board: Add alignment to fmem platform data

When fmem driver is initialized it will allocate from
allocate_contiguous_ebi_nomap (if the target is not using fixed
location for fmem) passing in an alignment value. The alignment
value is set in platform data for each target. However, the
alignment value was not set for several targets causing the
alignment to be 0 and the allocation from
allocate_contiguous_ebi_nomap to fail.
