This is a v3 posting of Saheed's ASPM cleanup.

The intent is that this is strictly cleanup, no functional changes at all.
We want to simplify the code by removing struct aspm_register_info and
pcie_get_aspm_reg().  These are only used to read and store register info,
but the info is only used in one place, so the function and struct only
make things more complicated.
