The ocelot_regfields struct is common between several different chips, some
of which can only be controlled externally. Export this structure so it
doesn't have to be duplicated in these other drivers.

Rename the structure as well, to follow the conventions of other shared
resources.

v1 from previous RFC:
* Remove GCB_SOFT_RST_SWC_RST entry from the regfields struct - it
isn't used.
* Export the vsc7514_regfields symbol so it can be used as a module.
