For whatever reason, the function pointer structs (and their retrieval
functions) were split up on data size boundary - separate for 16-bit,
32-bit, and 64-bit.

This makes the already tedious boilerplate require to deal with these
hardware quirks even worse, so unify them into a single function pointer
struct and retrieval function.

Meenakshi, Pankaj - I have no hardware to verify that this patch works,
but it builds cleanlyi and isn't exactly complex.
I will need R-b from at least one of you, and ideally Tested-by as well.
