Some of the parameters of used in display bandwidth calculations are
tied to the platform and are orthogonal to the display IP.  After talking
with the hardware team, we now have the information (and Bspec has been
updated) that the members deprogbwlimit and derating of struct
intel_sa_info are such platform-specific ones.

With that, we are now able to make the driver code more aligned with the
hardware by splitting structs intel_sa_info into two different structs:
one that is platform-specific and another that is display-IP-specific.

That change also allows us to simplify how we select the parameters for
the calculation.
