qed: Add abstraction for different hsi values per chip
The number of BTB blocks was modified to be different between the two chip flavors supported (BB/K2) as a result, this lead to a re-write of selecting the default hsi value based on the chip. This patch creates a lookup table for hsi values per chip rather than ask again and again for every value.
