Fix wrong density encoding on Intel Silvermont.
Silvermont (Bay Trail, Rangeley, Avoton) seems to still use the old
density encoding with 3 bits per chip. Documentation is unavailable
(held concealed by Intel) but thanks to the efforts of Tai-Hong
(Type) Wu the layout is clear now. This patch is based on his one
but solves the issue differently thus reducing the code complexity.
