We should have v3.15 working fine, but PM features are not merged in util for v3.16. I would try dding calls to omap_sdrc_init to pdata-quirks.c the same way board-over.c is doing: omap_sdrc_init(mt46h32m32lf6_sdrc_params, mt46h32m32lf6_sdrc_params); If the memory timings are not correctly set by the bootloader that could explain the issues.
