msm: board: Restore SF and MM heap to PMEM sizes

SF and MM heap are currently incorrectly sized.
Clients of these two heaps will run out of memory
and start failing.

Restore the SF and MM heap sizes to PMEM sizes. SF
heap will be 64MB if HDMI is configured as primary
otherwise 40MB. MM heap will be 66MB.
