ARM: dts: msm: disable memcg kernel and socket accounting on sdm670/710

Disable memcg kernel and socket accounting on sdm670/710 since
memory cgroups is used in this target as a means of user space
task grouping based on oom_score_adj, and controlling the userspace
memory consumed by tasks. Kernel and socket memory accounting is
not considered. Since memcg is created per process on this target
enabling kernel accounting results in the creation of numerous
kmem caches resulting in significant overhead.
