The device tree subnodes, and hardware, for the eccmgr are
the same for Arria10, Stratix10, and Agilex. Update driver
to allow the subnodes to be allowed for "altr,socfpga-s10-ecc-manager".

Please slap a comment above this here - one can see the difference between the
two calls only after staring at them for a couple of minutes and wonder
where's Waldo.

Adding a comment is a very good suggestion. On the other hand, Rob 
Herring and Krzysztof Kozlowski pointed out that this change represents 
a change in the ABI which should be avoided. This change won't be part
