Iterate over physical engines
We current have a single for_each_engine() iterator which we use to
generate both a set of uABI engines and a set of physical engines.
Determining what uABI ring-id corresponds to an actual HW engine is
tricky, so pull that out to a library function and introduce
for_each_physical_engine() for cases where we want to issue requests
once on each HW ring (avoiding aliasing issues).
v2: Remember can_store_dword for gem_sync
v3: Find more open-coded for_each_physical
