[sonic_sfp/qsfp_dd.py] Update DOM capability method name to align wit…

…h other drivers (sonic-net#163)

Update method name to align with other drivers. Change from `parse_qsfp_dom_capability` to `parse_dom_capability`. Other drivers were aligned via sonic-net/sonic-mgmt#2937.

When this submodule is updated in sonic-buildimage, all callers will need to be updated to reflect the new nomenclature.
