Joe LeVeque 78bf8159e8 [platform] Update QSFP method name 'parse_qsfp_dom_capability' -> 'parse_dom_capability' (#6695) 
**- Why I did it**
PR https://github.com/Azure/sonic-platform-common/pull/102 modified the name of the SFF-8436 (QSFP) method to align the method name between all drivers, renaming it from `parse_qsfp_dom_capability` to `parse_dom_capability`. Once the submodule was updated, the callers using the old nomenclature broke. This PR updates all callers to use the new naming convention.

**- How I did it**

Update the name of the function globally for all calls into the SFF-8436 driver.

Note that the QSFP-DD driver still uses the old nomenclature and should be modified similarly. I will open a PR to handle this separately.
