An improvement to the memory distribution logic was suggested
in which the variable that keeps track of doubling the amount
of memory per pass could be removed. This commit removes the
variable and introduces a couple of other small changes.

This change introduces the unit tests (and helper functions)
to test the SMF memory distribution algorithm.

Witherspoon (OpenPOWER) will run in native mode, which means
all the processors have to be at the same level
(all DD2.2 or all DD2.3). Other systems (ZZ) we support
running in a mixed configuration where DD2.3 processors will
be run in 2.2 compatibility mode. We also need to support
arbitrary OP systems that might want to run in compatibility
mode even without mixed parts.
See src/usr/hwas/common/README.md for the rules and resulting
mode.

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.

This change introduces the unit tests for testing the helper functions
of the SMF functionality to move the HOMER BAR to secure memory.

Logic for distributing the requested amount of SMF memory between
the procs with memory on the system. The algorithm attempts to
allocate the memory in power-of-two increments of 256MB (such
is the HW limitation) under each proc until the requested
amount is satisfied or until we run out of procs with memory.

This commits enables HOMER BAR to point to the top
of the secure memory on SMF-enabled systems. Consequently,
the HOMER image and hostboot reserved memory will
be moved to the secure memory if SMF is enabled.
