[PATCH 09/10] PCI: qcom: Clean up IP configurations

[Johan Hovold]

The various IP versions have different configurations that are encoded
in separate sets of operation callbacks. Currently, there is no need for
also maintaining corresponding sets of data parameters, but it is
conceivable that these may again be found useful (e.g. to implement
minor variations of the operation callbacks).

Rename the default configuration structures after the IP version they
apply to so that they can more easily be reused by different SoCs.

Note that SoC specific configurations can be added later if need arises
(e.g. cfg_sc8280xp).
