net: dsa: hide dp->bridge_dev and dp->bridge_num in the core behind helpers

Browse source 
The location of the bridge device pointer and number is going to change.
It is not going to be kept individually per port, but in a common
structure allocated dynamically and which will have lockdep validation.

Create helpers to access these elements so that we have a migration path
to the new organization.
