SMF: NVRAM Reading and Mem Distribution end-to-end Changes
This commit introduces the changes to read out the SMF secure
memory amount value from NVRAM and to distribute the secure
memory amount based on the value read. strtou64 was copied
from runtime code to convert the value read from NVRAM (as a
string) to uint64_t.
