This patch adds apollolake soc specific change. DPTF
ASL files are now in src/soc/intel/common so that
they can be reused but different soc can have different values
e.g., for skylake cpu soc thermal reporting device is at
Bus 0, Device 4, Function 0 while for apollolake it is Bus 0, Device 0,
Function 1. This patch adds a dptf asl file in soc directory where we
can define all values which can change across soc's and can be
included in mainboard dptf asl.

CAS latency detection also relies on this, and has been cleaned up.
Ram initialization does not work with FSB 1333MHz / DDR2 800MHz combination,
so disable this combination for now, and reduce to 667MHz instead.
Still don't know why this is the case, but FSB1333/667 works.
These changes should now allow existing configurations to continue working,
while providing support for previously unworking configurations, due to
previous buggy CAS latency detection code.
